Frequently asked questions
What is the difference between #AARRGGBB and #RRGGBBAA?
Android and many iOS helpers put alpha first (AARRGGBB). CSS puts alpha last (RRGGBBAA). Pick the order that matches where your code came from.
How is the text color chosen?
Brightness uses the YIQ formula (R×299 + G×587 + B×114) ÷ 1000. Above 0.5 the color is light, so dark text is suggested; otherwise white text.
Does 3-digit HEX work?
Yes. #ABC expands to #AABBCC.
