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.

Do both gray and grey spellings work?

Yes. The CSS standard includes both spellings, so gray and grey (and darkgray/darkgrey, etc.) both resolve to the same hex value.

Is anything uploaded?

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

Color Name to Hex Converter

This tool converts any CSS named colour — like cornflowerblue, teal, rebeccapurple or tomato — into its hex code, with a live swatch so you can confirm the colour. It is useful for designers and developers who know a colour by name but need the exact #rrggbb value for a design file, a config or non-CSS code that does not accept named colours.

How it works

The full table of 148 CSS named colours from the CSS Color Module Level 4 standard is built into the page as a name-to-hex map. When you type a name, the tool looks it up directly and returns the corresponding hex value plus a preview swatch. Both the gray and grey spellings are included, as is the modern rebeccapurple. If the name is not recognised, it tells you and suggests close matches that start with what you have typed.

Example

Named colour	Hex
cornflowerblue	#6495ed
teal	#008080
tomato	#ff6347
crimson	#dc143c
rebeccapurple	#663399

So typing tomato returns #ff6347 with a matching swatch. Lookups are instant and run entirely in your browser — nothing is uploaded.
