HTML Color Codes and Names

CSS defines 148 color names — from aliceblue to yellowgreen — that work in HTML, CSS and SVG anywhere a color is accepted. This page lists every one with its HEX, RGB and HSL code, grouped into color families, and lets you inspect any code: type a name to get its values, or type a HEX or rgb() code to see whether it has a name and, if not, which named color is closest.

How to use this tool

1. Type a color name or code into Color to inspect (or leave it empty).
2. Pick a color family, or keep "All 148 names".
3. Narrow the list with the filter — part of a name ("sea") or of a HEX code ("ff").
4. Sort by family, name, hue or lightness, then copy codes from the table or download the swatch chart.

Formula

Nearest name = the named color with the smallest CIEDE2000 difference ΔE₀₀ from the inspected color, both converted from sRGB to CIELAB (D50) as in CSS Color 4.

A ΔE₀₀ below about 1 is hard to see; 2–3 is a small but visible difference. Gray/grey spellings are skipped in the search because they duplicate their twins.

Example

Inspecting tomato gives #FF6347, rgb(255, 99, 71) and hsl(9.1, 100%, 63.9%); it belongs to the oranges, and black text on it reaches 7.12:1 versus only 2.94:1 for white. Inspecting #FF6348 (one step bluer) returns "tomato #FF6347 — nearest, ΔE2000 0.24".
