How can I change planet colors in a way Parallax understands?

[rheaunderstars]

I'm trying to retexture some planets. Right now I'm working on changing up Dres to make it brown and white instead of gray. But I'm having some trouble integrating it with parallax. I'm using both Kopernicus and Texture Replacer to swap out its colors. When I'm in deep space or map view, Dres looks brown. But when I zoom in and Parallax terrain loads in,  it turns gray again. Does anyone know how to change planet textures in a way that Parallax understands?  Is there a line of code I could add to a config file or something?
