Modify colors for time of arrival plot

[klotter]

Hello!

Using the command line for the time of arrival plot isochron.exe it always defaults to a rainbow color palette (from blue over green to red) and in my opinion the difference between neighboring contours is pretty hard to recognize in this plot.
However if I reduce the number of contours by passing '-n 7' or similar, the colors stay the same. Instead of picking 7 colors from the rainbow palette (where two neighboring ones would show larger differences, than for n=12), the colors stay the same as with a higher number of contours and the palette is reduced to blue to green.

Is there any option to change the color palette or colors that isochron uses?

Many thanks for the help!

At the moment, the isochron program does not have an option for changing its palette colors.
