Frequently asked questions

What text colour should sit on 616161?
Black gives 3.39:1 and white gives 6.19:1, so white wins at 6.19:1. That clears the 4.5:1 AA threshold for normal text, but not the 7:1 AAA threshold.

Do the CMYK numbers match a print workflow?
They are the naive conversion from RGB, which assumes no ink limit, no colour profile and no black generation strategy. Real print work needs a profile-aware conversion; the values here are the ones the converter reports and are best used as a starting point for a designer rather than a press-ready separations file.
