some of my small code modification on CalculiX GraphiX to support RedBlue and Gray color maps.
revision 1 : *replace RedBlue with CoolWarm colormap. *rename Gray colormap with GrayScale
*add (29 Sept. 2026) Rainbow Desaturated for CGX
ccxview colormaps added similar with CGX: Inferno, Jet, Grayscale, Rainbow-desaturated & classic
