Color blindness helper algorithm -


what algorithms accessibility colorblind people? i'm guessing color reduction help, can't find information on internet other smartphone apps (not papers).

rationale: recently, crt monitor stopped outputting magenta, after little research seems bit similar how tritanopia sees. basically, in red spectrum output shades of blue. although buy new monitor, i'd know software-based fix; situation has got me interested in building accessible applications.

the best way solve legibility problems folks color blind increase color contrast ratio. web content accessibility guidelines require minimum contrast of 4.5:1 (3:1 large text).

there handful of contrast analyzers out there. google's accessibility developer tools includes algorithms checking contrast , recommending alternatives.

if inclined, use library create browser extension dynamically changes css on page make content meet required contrast ratio.
