Frequently asked questions
What text colour should sit on E91E63?
Black gives 4.83:1 and white gives 4.35:1, so black wins at 4.83:1. 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.
