Color blindness helper algorithm
accessibility, algorithm, colors
Solution
The best way to solve legibility problems for folks who are color blind is to increase the color contrast ratio. Web Content Accessibility Guidelines require a minimum contrast of 4.5:1 (3:1 for large text).
There are a handful of contrast analyzers out there. Google's Accessibility Developer Tools includes algorithms for checking contrast and recommending alternatives.
If you were inclined, you could use this library to create a browser extension that dynamically changes CSS on a page to make content meet the required contrast ratio.
Problem
What are some algorithms that help accessibility for colorblind people? I'm guessing color reduction could help, but honestly I can't find much information on the internet other than smartphone apps (not even papers). Rationale: Recently, my CRT monitor stopped outputting magenta, so after a little research this seems to be a bit similar to how someone with tritanopia sees. Basically, anything in the red spectrum will be output as shades of blue. Although I could buy a new monitor, I'd like to know a software-based fix; this situation has got me interested in building accessible applications.
