[Help] How do I change the color of a set?

[jumongski]

Below I have couple of sets. I want to change the orange/yellow color to something similar to original item color. For example for Set 1 the original color is black with item level +0 now when I make it +15 it became gold. I want it to make it dark white color like black dragon set +15.

I'm not expert but you can try find something like CustomItem ("GetMainInfo" for search) and there try to change RGB numbers.
Also for best quality you need recolor object files.
