Color Changes in Mac OS X for the Visually Impaired?

Cliff posted more than 11 years ago | from the wanted:-light-text-on-dark-backgrounds dept.

Graphics 87

drdink asks: "I am an avid FreeBSD and Windows user. This semester for a class I'm having to use MacOS X for the first time, and I've also been pondering jumping into the Apple scene anyway. However, I am also visually impaired and I can't seem to find a way to do specific color theming in a way similar to Windows, KDE, and GNOME. I want to be able to say 'Text is white, backgrounds are black, but EVERYTHING ELSE is its normal color.' The only options I've found that are similar is using 'White on Black' in the Universal Access control panel. However, this results in me losing all display colors and my machine looking monochrome. I don't want to use a $2,000+ machine just to have no colors. Is there anybody out there who has actually managed to get Mac OS X to use the normal colors but have high contrast white on black dialog boxes? I am interested in the Apple platform, but I can't use it for useful things, if I have no color."

ZackSchil (560462) | more than 11 years ago | (#6864852)

You can switch to white on black, then change the number of colors back to Millions. It gets you back your coler and keeps everything reversed. Problem solved.... well, if you don't mind using a negative of aqua :^D Gotta love the orange buttons.

Well, technically, in Photoshop you can simply invert the colors just before saving them. But you're right, that's not a very good solution. LOL

Not only a nice prank, but may be of some help to the poster.

Hit Control+Alt+Apple+the star on the num pad. It will switch your display into grayscale and invert it. Under MacOS X 10.3 you will have to press Control+Alt+Apple+8

It obviously won't leave everything else as a normal colour, but you'll get your white text on black background. Hope that helps some!

Switch to Millions and then 256- better contrast! (2, Informative)

14cfr01 (626507) | more than 11 years ago | (#6868763)

I know this sounds stupid, but:

For better contrast, switch to Millions of colors and then switch back to 256 colors.

This results in an inversed color screen that is much more readable. I think using 256 colors will be more helpful to the visually impared user; I was having lots of trouble reading text on the inverted screen under Millions of colors.

Thanks for the tips! I didn't know you could do this! I'll see how much work I can get done before I've gotta switch the screen back.

There is a company that has a product that can produce any desired colours on any screen. I believe their name is Crayola.

Re:Solution (4, Funny)

drdink (77) | more than 11 years ago | (#6864934)

I just checked. Crayola only supports a 120-color display with their Crayon product line. I think this is a far cry from the 32bpp I would expect from Aqua.

Re:Solution (1)

karmavore (618727) | more than 11 years ago | (#6864963)

You can use a device called a candle to provide heat to allow colours to be mixed thereby producing other colours. However, there have been some reports of technical difficulties with LCD displays.

xcarroll (704121) | more than 11 years ago | (#6893804)

I thought Crayola were working a technology called colour-mixing? It's a bit like anti aliasing: you combine some of the 120 colours and suddenly it looks you've got new intermediate shades. There's probably an OpenGL function call for it.

Theme Park Tutorial [geekspiff.com]

What does this mean? Make your own. While I'm not familiar with the creation process for other windowing systems (like you mentioned) I do know that you can probably make your own theme to specifications you desire. Those links are where I would start; perhaps there's something there that you can modify or a theme that fits the bill without changes.

Good luck!

Re:Here's two resources... (1)

dave1212 (652688) | more than 11 years ago | (#6876034)

Why does drdink not reply to this? Did he not find these links useful? I've been using themes on my Mac since 10.1 for a number of different reasons with great success.

This sounds like what he is looking for, but even though he posted another response five minutes before glowurm's comment, he didn't seem to catch this one.. odd.

Hopefully the links will help direct him to where he can find some help.

If you do catch this, drdink, the app that has worked for me with all the themes i can throw at it is called ThemeChanger. Find it here [versiontracker.com] .

As more people create quality themes, the value of this sort of utility keeps growing. I bought a Kaleidoscope [kaleidoscope.net] license way back when -- alas, MacOS 8.x - 9.x only -- the tons of excellent themes made it worthwhile.

That is much easier said than done. When it comes to big companies like that, it can be hard to find the right person to contact who would be interested enough to follow through on the issue. Since I don't actually own Apple hardware or software at the moment, their desire to help me will be lessened even more. I was going to use that as a very final last resort, since it will likely involve being transferred all around the company and being put on hold for 77 hours. Not to mention that one would think if they had an answer, it would be online already.

igabe (594295) | more than 11 years ago | (#6865186)

If you can't work without the black and white you talked about, then how can you can you still see "everything else"?

OS X's Aqua GUI has a lot of white, and now with Panther(Apple's fast approaching major OS update) coming out, brushed metal(metallic darkish grey) is going to be everywhere. Just not sure how that is going to look with any solution you may find.

Re:Curious (4, Informative)

drdink (77) | more than 11 years ago | (#6865772)


If you can't work without the black and white you talked about, then how can you can you still see "everything else"?

It is more of an issue of contrast. I can see white on black so much easier than black on white. Since there is less white blazing out at me, it is easier to see the text. I can see black on white, but it causes eye strain much faster and takes a lot more effort to read. Having the majority of my 'readable' screen area in high-contrast colors saves my eyes from catching on fire after a while.

Scotopic Sensitivity (2, Informative)

yroJJory (559141) | more than 11 years ago | (#6880557)

Have you ever been tested for Scotopic Sensitivity Syndrome (SSS) [irlen.com] ? This may be a better way to correct the issues you are having, as the solution uses color overlays or colored lenses to limit the amount of light entering your eyes. For example, if you see letters jiggling when reading a book, it is a sign that you may have this problem.

The Irlen Institute [irlen.com] has done quite a bit of research about this and I can tell you from both my experience and observation that it works. After all, if the problem is occuring when using a computer, I imagine reading a book (if you ever do so), must be incredibly difficult.

My mom is a reading specialist and she has been testing people for SSS since I was in grade school. The difference between the reading abilities of her students was immediately noticable. I highly recommend looking into SSS testing.

Newer Panther Options (4, Informative)

A new panther feature lets you increase the contrast of the entire screen any desired amount (until you basically get everything, 100% white, black, RGB, CMY)
Also current versions support a nifty zoom in feature.

Re:Newer Panther Options (4, Insightful)

drdink (77) | more than 11 years ago | (#6865752)

The zoom functionality in OS X kicks ass. It makes the stupid Magnifier in Windows 2000+ look like a piece of crap... oh wait, it is. However, I think I could get along well without zooming were the screen a higehr contrast (white on black). That is how I operate in every other GUI right now (Windows, KDE, GNOME, ...). It is sort of saddening to see how difficult it is to do the equivelent in OS X. I haven't seen the contrast setting, but I've heard of it. Is this something that is currently in 10.3 snapshots?

RzUpAnmsCwrds (262647) | more than 11 years ago | (#6866132)

And GTK+'s fully-adjustable font sizes with automatic resizing makes any kind of zooming applet look like a piece of crap.

Windows does this too, although not as elegently.

Oh, and the "new" contrast enhancing functions of OS X have been in my NVIDIA drivers since 2001. You can adjust brightness, contrast, gamma, and there's a control called "Digital Vibrance" that makes colors more pronounced.

Re:Newer Panther Options (2, Insightful)

Anonymous Coward | more than 11 years ago | (#6866184)

yes it's given that the 'contrast' feature is just like digital vibrance control, graphic cards, and software have been doing these features for year, yes, all true.

The wisdom comes from putting this control under Accessibility Options, and not placing it in the colour syncing utilities.

Windows has had contrasting features, in the order of a colour scheme and big fonts, OSX also features the ability to speak to the user the text under cursor, dialogue and so on, software which costs $2500 AUD when I asked the RBS of Australia for an equivalent software package for windows.

Using the existing electronics to alter colour profiling on the screen is not new (certainly before 2001, when nvidia gave out glossy images stating that digital vibrance control did more than up the contrast to unusuable levels.) Both these responses sound like windows zealots urinating some territory rather than actually addressing the initial question.

P.S. For your windows flame, OSX is already standardised on features than windows users won't see until long after 2005 has passed.

Wow... don't you feel mature using words like "urinating". And what exactly do you mean by "standardised on features than windows users won't see until long after 2005 has passed"? I think that you're saying that OS X has features that XP won't have for some times. Of course it does. And XP has features that OS X will NEVER have - DirectX, Windows Media Player 9, Internet Explorer (not the crappy Mac version). Now, does OS X have equivelents to these features? Yes, of course it does. But they're still features that OS X "lacks".

What's new in Panther? Fast user switching, an encrypting filesystem, share synchronization. Three features that XP already has. Oh, and a new finder - it's metal now. Amazing. Oh, and a chat client with video. Sounds like XP. About the only really new feature is expose. Wow. Now I can get little previews of all my windows. XP's powertoys includes a nice little plugin that adds image previews to ALT+TAB. Or you could just look at the taskbar - it gives you nice descriptive text labels.

I don't think this is worthy of Insightful. Come On! Have you any clue what is baked in the next release of Windows. A bunch. One little thing of many that I look forward to is that you can have a higher resolution on your screen without the output coming out so you need a magnifying glass to read the screen as the text is so small.

Re:Newer Panther Options (1)

drdink (77) | more than 11 years ago | (#6866369)

OS X's zooming does much more than just changing font sizes. It is the equivelent, sort of, of setting a low resolution in X but having a large virtual desktop. It is very much like how all commercial screen magnifiers for Windows function. Font resizing can't touch teh usefulness and accessability of the full screen zooming.

This doesn't do specifically what you're asking, but it may be useful to you, even if only for fun.

Open Terminal and enter the following command.

This command sets a preference that reverses all color polarity on the screen (like a photographic negative). I think you'll have to reboot or at least log out and back in to see the results. Of course, changing the -bool YES to -bool NO will return your display back to normal.

Total colour control (2, Interesting)

mrthoughtful (466814) | more than 11 years ago | (#6868466)

You can obtain total control over the screen colour by using an ICC colour profile for your monitor.

The profiles live here.

I (Ben) even wrote a freely available ICC profile editor back in 1995. You can find it on this stranger's [boscarol.com] page.

Amazing. it still works. (on OS 9) - I lost all the source code, so it never got beyond beta, and it will never get to OSX. Although it was released under shareware, there used to be an accompanying note that said it is now freeware, but this guy has an old copy.

``Dark Adapted'' utility useful for this (4, Informative)

It's intended for astronomers so as to preserve their night vision, but is fully configurable.

Free too.

Since Apple "Steve'd" the disability solutions group at Apple, solutions for the "differently'abled" have been declining or slow to come.

As far as disability solutions are concerned, Mac OS X is not as mature as Mac OS 9 was.

Making ColorSync color blind (3, Interesting)

mckeever (410646) | more than 11 years ago | (#6870212)

During WWDC this year, one of the presenters showed how certain files can have ICC profiles embedded in them that can translate the color palette in radical ways. They were using this to verify that apps were using colorsync correctly and not double applying it. After this, I started digging and (in Panther, anyway) you can use ColorSync Utility to install custom output filters to adapt colors any way you like.

For instance: They include an output filter for CMYK (4-color printing) that prints everything in sepiatone.

There's absolutely no reason at all that this facility couldn't be used to do some funky color translations for the screen to help color blind people see it better. Obviously, this would require a better knowledge of the various types and degrees of color blindness than I have, but it could be useful to many and should automatically effect all apps on the machine

iCal coloration (2)

ekc (594380) | more than 11 years ago | (#6872672)

I am partially color-blind myself, and have difficulty distinguishing iCal entries by calendar color due to the particular shades Apple has chosen. Anyone know how to tweak these?

-Ted

P.S. While I'm at it, I woudn't mind hearing about any trick for inverting the color scheme at arstechnica back to something sensible!

You can request this feature at:
http://www.apple.com/macosx/feedback/

Or:
http://www.apple.com/feedback/ical.html

There is a feedback page for just about every iApp and for Safari. There are links to them from the App's application menu.

The color values for iCal can be altered by opening the application package and changing the values in info.plist

(working from memory) or maybe it might have been ~/Library/Preferences/com.apple.ical.plist instead. Hmmm pretty sure it was the first one.

I'm on a Win2000 box at the moment so I can't check it for you.

Black Light (2, Informative)

You might want to see if the effect this application [ulaval.ca] produces (essentially inverting the gamma curve) assists you at all.

Epilepsy (1)

artspraken (104283) | more than 11 years ago | (#6886940)

I am epileptic. I find a mass of white light very aggravating. This problem is less with LCD with less flicker, but my tendency to attacks during extended sessions in front of the computer is less when I use a black background. In my situation, I have always used a background that is black.

I have been on white on black in windows, but since converting to OS X I have not found a suitable alternative.

I hope Apple will squarely address this for us epileptics, if only to allow us to remain on computers for longer periods.

not a profile change (0)

Anonymous Coward | more than 11 years ago | (#6892001)

he doesnt want the screen inverted he just wants to specify that the gui created windows and such (ie my note pad and web browser favorites bar) would be white text on black rather than black on white.... doing a color profile would hose everything he looks at on the comp! i dont know of a solution but it sounded like there needed to be some clarification on what was clearly being asked

System Preferences and BackLight are what you need (1)

giaguara (632198) | more than 11 years ago | (#6897062)

Go to System Preferences, and Choose Universal Access. You can turn on zoom that can zoom that is practically illimited. You can manually zoom what you need to see better in any application after that.

alt command + zooms in
alt command - zooms out
alt command * switches zoom on / off.

You can also choose the background and text colors to be more visible for you.

There is also an external application called BackLight. It inverts the colors you have on the screen. Many even normal sighted people sometimes find it useful.

haxie or Input Manager? (1)

sapporo (552550) | more than 11 years ago | (#6898944)

It should be possible to modify the default colors of all text fields (via a haxie or Input Manager). Would that help? For Safari, maybe you could use a custom stylesheet. What other apps do you need modified? Cheeers, -sapporo.
