HEX to RGB online — and back, plus HSL
HEX ↔ RGB ↔ HSL converter online, OKLCH and WCAG contrast. Screen eyedropper in Chrome.
Type #ff7e15, #f80, tomato or rgb(255 126 21) and the other formats update at once. A half-typed HEX does not snap the preview back to the default until the string is valid.
HEX8 (#rrggbbaa) and the alpha slider set transparency. oklch() is ready to copy for modern CSS.
Contrast against white and #000000 shows whether body text passes AA (4.5:1) or AAA. This is screen RGB, not CMYK for offset print.
#ff7e15 is rgb(255, 126, 21). The short form #f70 expands each digit, so it is #ff7700, not a rounded version of the long orange. Alpha in #ff7e1580 is the last byte, about 50% opacity, and plain rgb() has no place for it: use rgba. HSL is a different model of the same colour and is not required for this conversion. Contrast against white or black is a separate check on the colour tool. This page opens the picker on the hex and rgb pair.
