A table of standard color names and values for the first intermediate n-ary hues of the additive RGB and CMY color models, at full saturation and value. In standard sRGB, converted between HSV, the total number of hues is 255 (0° <= N <= 360°).
Hover over an underlined hue for a list of some alternative names. Items in gray are tentative or placeholders. For more details, click the link at the bottom of the page.
Entry format. Each entry in the hue table is shown in various formats, indicated by the column name. Normal is the value from 0-1 inclusive, to three fractional digits. Percent is 0-100%, to two digits. Angle is 0-360°, to zero digits. Decimal is 0-255, to three digits. Hex is #000000-FFFFFF, to zero digits.
Calculation. Hue values are calculated when the page loads, using a special script. Hues are generated by taking standard RGB color values and converting them between the RGB and HSV color models, as double-precision floating point numbers. The final values are rounded to a specific number of fractional digits for display. The final preview swatches are displayed using your web browser's default color profile; this should be standard sRGB with nonlinear 2.2 gamma, but may differ if advanced color management is in effect.
Range. Conventional 8-bits-per-channel (24-bit) color cannot represent any hues beyond octonary. However, the human eye cannot easily distinguish hue differences below 1%, making the naming of hues beyond senary redundant.
Source. Hue names for primaries through quaternaries are from de-facto convention and tradition. Hue names beyond quaternary are selected via careful, informed methodology from several aggregated sources, as noted below. Additional details can be found in the source code of this page.
Standard. This collection does not constitute an official standard as recognized by a major standards group, but may serve as a proposed de-facto set for the purpose of industry uniformity and individual convenience.
