Quick answers
Frequently asked questions
Which color values can the converter read?
Enter a three- or six-digit hexadecimal color. Matrix reports the matching RGB and HSL values plus contrast against white and black.
Do the contrast results guarantee accessible text?
The ratios test the chosen color against white and black using WCAG thresholds. Actual readability also depends on font size, weight, and the real background.
