Browse all 148 named CSS colors with HEX values, color swatches, and search filtering.
This chart is a finite lookup table for the CSS named-color vocabulary, presented as 148 searchable rows. Each row places the keyword beside its six-digit HEX value and a rendered swatch, letting a user check spelling, numeric equivalence, and approximate appearance in one view. Entering a name filters the displayed set instead of converting a free-form color. The point most often missed is that 148 names do not represent 148 unique colors: aliases exist, including aqua and cyan, which both correspond to #00FFFF.

Input
rebeccapurple
Expected output
A matching entry for rebeccapurple showing #663399 and a purple swatch.
The CSS keyword rebeccapurple is defined as #663399. Its hexadecimal byte pairs are 66, 33, and 99, equal to RGB channel values 102, 51, and 153 respectively.
Every row pairs one CSS keyword with its fixed hexadecimal sRGB equivalent and a visual sample. Typing an exact keyword such as rebeccapurple filters the chart to the relevant entry. The result is a lookup, not a color calculation: the chart reports the value assigned to that name and does not generate a new shade or modify the submitted text.
Names are counted as keywords even when two names have identical channel values. Aqua and cyan both map to #00FFFF, while fuchsia and magenta both map to #FF00FF. Gray and grey spellings also occur in several keyword pairs. Consequently, the number of chart entries is greater than the number of distinct colors represented by their HEX values.
Yes. A listed name is a CSS color keyword, so it can be used where a CSS <color> value accepts named colors, for example color: rebeccapurple;. The listed HEX value denotes the same color. This chart does not determine whether the choice has sufficient contrast, fits a project's design-token rules, or is supported by non-CSS software.
On this page, "HTML color names" refers to the standardized named colors used in CSS, not to a separate 148-color palette defined by HTML. Older references may emphasize a smaller historical group, while this chart states that it covers 148 names. No, each name is not necessarily a unique color because standardized aliases can share one HEX value.
