Help: how to define a color scale transition method?

Dear Prof Lu:
I want to select color scale transition method for displaying the electron density.
In Multiwfn 3.8 software, the color transition method is following:
0 Rainbow with black/white for values exceeding lower/higher color limit
1 Rainbow
2 Reversed rainbow
3 Rainbow starting from white
4 Spectrum (Pink-Blue-Green-Red)
5 Reversed Spectrum
6 Grey (Black-White)
7 Reversed Grey
8 Blue-White-Red
9 Red-White-Blue
10 Blue-Green-Red
11 Red-Green-Blue
12 White-Darkred
13 Black-Orange-Yellow
14 White-Dark green
15 Black-Green
16 White-Dark Blue
17 Black-Blue-Cyan
18 Viridis
19 Yelllow-Orange-Black

I want to know how to define a color scale transition method like "individual color A -white-individual color B", for examples, Blue-white-Green, Green-white-Orange, grey-white-iceblue, ...
Is there a keyword used to define a color scale transition method in the file of "settings.ini"?

Thanks in advance!

Hello,

The color transition methods are hard-coded, you cannot change it without modifying source code. Please look at plot.f90 in source code package, in which "subroutine setcolortable" contains the code for defining the coloring transitions.
