<table cellspacing="4" cellpadding="2" class="cmd">

== Description ==
{{cmd|definecolorgroup|[myblue][rgb][0:0:1,0:0;0.6,0:0:3]}} defines three colours {{code|myblue:1}}, {{code|myblue:2}}, {{code|myblue:3}}. If one defines similar gamuts for e.g. green and red, such that equal numbers correspond to equal grayscales, one can easily pick a red, a green, and a blue so that the colours still differ from each other when converted to grayscale.
 
ConTeXt has predefined colorgroups for red, green, blue, cyan, magenta, yellow, and gray; these are defined in {{src|colo-rgb.mkii}} for MkII, and {{src|colo-imp-dem.mkiv}} ('dem' for 'demo')for MkIV, and may be imported with {{cmd|usecolors}}.
 
== Example ==
<context source=yes mode=mkiv>
% mode=mkiv
\usecolors[dem] % use predefined demo colors
== Description == % NB: The grayshades of this colorgroup are not calibrated% to the ones in colo-imp-dem.mkiv\definecolorgroup [orange] [1.00:0.85:0.80, 1.00:0.80:0.30, 0.80:0.50:0.00]
