I, too, am severely chromatographically challenged.
At a former employer, I wound up being a part-time guinea pig for our UX staff - to the best of my knowledge, we were the only major SCADA player to have dedicated GUI colour schemes for colour deficients.
The downside? A number of phone calls to our support hotline made by customers who had accidentally switched to, say, the tritanopia-optimized palette. They generally went along the lines of "Geez, did you guys hire some colour-blind dimwit to do your displays?" -"Matter of fact, we did." -"Oh."
- leipert 9y agoWe recently had a look at these palettes: * Article: http://mkweb.bcgsc.ca/colorblind/ http://mkweb.bcgsc.ca/colorblind/ * 7-color palette: http://mkweb.bcgsc.ca/colorblind/img/colorblindness.palettes.trivial.png http://mkweb.bcgsc.ca/colorblind/img/colorblindness.palettes... * 12-color palette: http://mkweb.bcgsc.ca/colorblind/img/colorblindness.palettes.simple.png http://mkweb.bcgsc.ca/colorblind/img/colorblindness.palettes... * 15-color palette: http://mkweb.bcgsc.ca/colorblind/img/colorblindness.palettes.png http://mkweb.bcgsc.ca/colorblind/img/colorblindness.palettes... Can you or the grandparent elaborate whether they are working for you? We always try to combine color with an icon, e.g. green - check vs red - X, so that people having problems with colors are able to differentiate.
- extra88 9y agoYes, it's best to avoid using color alone. From the Web Content Accessibility Guidelines (WCAG): "1.4.1 Use of Color: Color is not used as the only visual means of conveying information, indicating an action, prompting a response, or distinguishing a visual element." [0] BTW despite the name, the WCAG are useful for non-web design.

- lb1lf 9y agoI am tritanope, with a (very mild) deuteranopia on top for good measure. The 7-colour palette works well - I can see seven separate hues (well, eight if you count the black.) The hardest ones to tell apart are the vermillion and reddish purple - I don't think I'd be able to tell the difference unless I had both in front of me simultaneously. The 12- and 15-colour palettes don't do much for me. Kudos for not using colour as the only cue!
- DigitalJack 9y agoI can tell the Bluish Green from Reddish Purple if they are side by side, but in isolation, I wouldn’t know which was which. This is on the 7 color scheme. I didn’t look at the others.
