Frequently asked questions
What text colour should sit on FF7F50?
Black gives 8.40:1 and white gives 2.50:1, so black wins at 8.40:1. That clears the 4.5:1 AA threshold for normal text and the 7:1 AAA threshold as well.
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.
