At the last #WordPress meetup @wp0711, @bovelett gave a presentation about #accessibility and we took the opportunity to test our websites.

Surprisingly, we had some contrast errors in our buttons despite using a #SCSS function to automatically calculate the correct contrast.

Turns out, most contrast calculation functions for SCSS are incorrect according to the WCAG 2 specifications.

So I found a smooth solution for that:
