Convert HEX, RGB, HSL and CMYK colors and check contrast

Options you can set

• Uppercase HEX

Good to know

• Accepts #rgb, #rgba, #rrggbb, #rrggbbaa, rgb()/rgba(), hsl()/hsla(), hsv(), cmyk() and the 148 CSS color names. Enter one color per line for several.
• CMYK here is a simple formula without a printer profile, so printed colors can differ.
• HSL, HSV and CMYK are rounded to whole numbers for display. Contrast ratios are rounded down, so a color is never shown as passing when it doesn't.
• Contrast follows WCAG 2.1: AA needs 4.5:1 for normal text and 3:1 for large text; AAA needs 7:1 and 4.5:1.
