Which colour names are supported?

All 148 CSS named colours from the CSS Color Module Level 4 standard, including modern additions like rebeccapurple, plus both the gray and grey spellings.

What if I mistype a name?

If the name is not recognised the tool says so and suggests close matches that start with what you typed, so you can pick the right one.

Is anything uploaded?

No. The colour lookup table is built into the page and runs entirely in your browser — nothing is uploaded.
