FAQ

Why is my 3-digit HEX auto-expanded?+
3-digit HEX is shorthand for the 6-digit version (#abc → #aabbcc). The tool normalizes to 6 digits so the value matches what CSS actually parses.
What does the contrast ratio mean?+
It is the WCAG luminance contrast ratio between your color and pure white or black. 4.5:1 is the AA threshold for normal text; 7:1 is AAA.
How is the palette generated?+
It takes the base color's HSL value and shifts lightness in ±20% and ±40% steps, keeping hue and saturation constant.
