Module:Color/doc

This is a documentation subpage for Module:Color.
It may contain usage information, categories and other content that is not part of the original module page.

This Lua module is used on approximately 620 pages and changes may be widely noticed. Test changes in the module's /sandbox or /testcases subpages, or in your own module sandbox. Consider discussing changes on the talk page before implementing them.

This module is used primarily by {{Infobox color}}, eliminating the need for external color converters and preventing mismatch between color coordinates.

Usage

To use this module, you may use one of the above listed templates or invoke the module directly. All functions that accept hexadecimal triplets also handle the shorthand three-digit format.

To convert a hexadecimal triplet to an RGB triplet as comma-separated values:

{{#invoke:Color|hexToRgbTriplet|color}}

To convert a hexadecimal triplet to the CMYK color model without a color profile (which is a very bad idea!):

{{#invoke:Color|hexToCmyk|color|precision=?|pctsign=?}}

To convert a hexadecimal triplet to HSL or HSV:

{{#invoke:Color|hexToHsl|color|precision=?}}

{{#invoke:Color|hexToHsv|color|precision=?}}

To convert a hexadecimal triplet to the perceptual CIELCh_uv color space:

{{#invoke:Color|hexToCielch|color|precision=?}}

To mix two colors in the more physically correct linear RGB space:

{{#invoke:Color|hexMix|color1|color2|proportion|min=?|max=?}}

To convert an RGB triplet to a hex code:

{{#invoke:Color|rgbTripletToHex|r|g|b}}

The following parameters are optional:

precision: defaults to 0 (zero)
pctsign: set to 0 (zero) to suppress percent signs in the generated output
proportion: proportion of color2, defaults to 50
min: minimum value of proportion range, defaults to 0
max: maximum value of proportion range, defaults to 100
