Occasionally the outer box will provide a color chart and/or the instructions will provide this, sometimes in detail and sometime more or less a list. I admit, I'm more of "vague" painter, If I like another color better and feel it will work well, I'll use it. Or I'll mix up something that works for me. I just painted an older kit that specified the moulded in color although for me it was all wrong. I ended up with a gloss aluminum spray from Tamiya which sprayed well and matched my expectations. Good luck, enjoy the build.
