RAL color system (Deutsches Institut für Gütesicherung und Kennzeichnung)
approximate RGB colors (inofficial translation from [http://www.ralcolor.com www.ralcolor.com]). These are defined in {{src|colo-imp-ral.mkiv}} and can be loaded using
<texcode>\usecolors[ral]</texcode>
== Solarized colors ==
Colors based on the [http://ethanschoonover.com/solarized Solarized] color schemeby Ethan Schoonover.
These are defined in {{src|colo-imp-solarized.mkiv}} and can be loaded using
|mistyrose||bgcolor="ffe4e1" |

== Using colors in MetaPost ==
A color defined in TeX is available in MetaPost using `\MPcolor{...}`or in LuaMetaFun simply the name in quotation marks. For example:
{|
|<context mode=mkiv>
\definecolor[highlight][r=0.8,g=0.8,b=0]
\color[highlight]{Highlighted text in TeX}
|}

== Calculating RGB Values ==
An example of how to use LMTX to calculate RGB values is the following:
<texcode>
% Use a color picker to get red, green and blue values of a color:
% Example: RAL 2005: red = 255, green = 35, blue = 1
% Create variables from the values:
\setvariables[ColorName][r=255,g=35,b=1]
% Do some magic:
\usemodule[mathfun]
% Define the actual color based on variables:
\definecolor[ColorName][%
r={\mathexpr[.3N]{\getvariable{ColorName}{r}/255}},
g={\mathexpr[.3N]{\getvariable{ColorName}{g}/255}},
b={\mathexpr[.3N]{\getvariable{ColorName}{b}/255}},
]%
% Test it:
\startTEXpage[offset=5mm]
\framed[foregroundcolor=white, background=color, backgroundcolor=ColorName]{Hello WORLD!}
\\\colorcomponents{ColorName}
\stopTEXpage
</texcode>
