Understanding color contrastSeptember 5, 2017 at 4:31pm
Hey all, I’ve been really struggling with trying to understand color contrast so I attempted to build a tool that shows you what regions of the color picker are accessible and what ones aren’t. It will even display what the nearest set of accessible colors are. I would love to know what you all think of it! http://kevingutowski.github.io/color.html
Heres an example of how it works:

Nice, thats a cool one Hannah! I like how they show you the various levels of accessibility and let you know what passed or failed.
I also like how you have the "lightness" slider to help make adjustments but its not quite clear to me what "lightness" means. Is it just increasing the R,G,B values or is it increasing the brightness value?
Cool tool! I met a guy in my program today who is studying visual design but is colorblind. Would teams see it as an asset to have a member that was colorblind? Would this be even better than a tool?
Even better, is anyone a colorblind designer that would like to chat?

Hey all! I just took a design pass at this page I think it looks much better. Hopefully it is a bit clearer to use!

Thanks for sharing, ! I've been working with Stark in Sketch, but I love that I can use this no matter the design system I choose to work in. 💜
