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]
