Hex to RGB

Enter a 6-digit hex color such as #ff0000, or enter red, green, and blue from 0 through 255. The converter writes the other form and shows a preview swatch.

#ff0000 is rgb(255, 0, 0). Short 3-digit hex and named CSS colors are not parsed here, so a stray letter becomes an error on the hex field instead of a guessed color.

Color questions

What is #ff0000 in RGB?

rgb(255, 0, 0). The first two hex digits are 255, and the other channels are 0.

Can I omit the hash mark?

Yes. ff0000 is accepted. The result still writes #ff0000, so the two forms stay easy to copy.

Why is #fff rejected?

This converter reads six digits only. Expand it to #ffffff if you mean white.
