Complicated color change

[jaka1-newbie]

With ColorFuzz we can make another color with near colors.

But can we do difficult changes.
From one group color to another?

I might be better to ask your question here instead: https://github.com/ImageMagick/ImageMagick/discussions. And if you get an answer I can help you translate this to C#.

Thx. Try there.
I think - may be we can grayscale 1 image - make from it mask - and compare with new color...

Happy to see that you got an answer. I probably won't be able to translate the code before Friday. Would you mind giving it a try first yourself and ask for help here when you need it? Most options on the comand line are methods of the MagickImage class.
