(a mismatch between RGB math and human perception..) I believe the white text "pops" WAY MORE than the black text.. but, the algorithm we use today disagrees..

what do you think?!

explore how a small change to purple can convince the algorithm otherwise

I find this pretty frustrating pretty often..

thanks @mayabenari for this share, a tool that includes luminance information in the comparison and is making (or made) efforts to help these color scenarios https://www.myndex.com/SAPC/ 

another killer share from @mayabenari, Editor's draft that includes updates to the WCAG contrast algorithm https://w3c.github.io/silver/guidelines/#visual-contrast-of-text and a link to the updated algorithm in js https://github.com/Myndex/SAPC/blob/master/JS/SAPCsRGB.js
