Frequently Asked Questions
What color formats are supported?
Tools support HEX (#RRGGBB), RGB (rgb(r, g, b)), HSL (hsl(h, s%, l%)), and HSB/HSV. The Color Picker converts between all formats instantly as you pick a color.
What does the WCAG contrast checker do?
It calculates the contrast ratio between two colors and checks whether the combination meets WCAG 2.1 accessibility standards: AA (4.5:1 for normal text) and AAA (7:1 for normal text). This is essential for accessible web design.
Can I generate a palette from an existing color?
Yes. The Color Palette Generator takes a base color and generates complementary, analogous, triadic, and monochromatic palettes. You can copy individual HEX codes or export the full palette.
