: How to rotate colors correctly I need to "rotate" colors depending on a certain dependency, how do I calculate this? I'm using no program, just working with a bitmap in C# For example: Every

This is a complete stab in the dark, but here is what I would try: The HSL values are 200/100/35 and 0/100/76, so rotate the value of each H value by 200° and add 41% to each L value (clipped at 100).

More information from thebodzio's comment:


I think what you really have in mind is “mapping”. In that regard it's
like any other mapping between two vector spaces (with some
clipping/wrapping; not necessarily bijective process). The problem is,
there's infinitely many such mappings. You just have to formulate one
that suits you best. @JohnB 's proposition seems to be the most
reasonable in that regard, however it requires conversion from RGB
(sRGB?) to HSL and back. Algorithms are easy enough to find.
