Description
\definecolorgroup[myblue][rgb][0:0:1,0:0;0.6,0:0:3] defines three colours myblue:1
, myblue:2
, 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 colo-rgb.mkii for MkII, and colo-imp-dem.mkiv ('dem' for 'demo')for MkIV, and may be imported with \usecolors.
Example
% mode=mkiv \usecolors[dem] % use predefined demo colors % 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] \definepalet[mypalet] [myorange=orange:2, myred=red:4, myblue=blue:6, mygreen=green:8] \showcolorgroup[orange] \comparepalet[mypalet]
