You paint in a different layer. The real trick isn't "how do you paint", it's "how do I extract the ridges from the original paint", which is a bit more complex & needs some knowledge of what paint packages are capable of first ( ie, practice ). But basically you're aiming to remove the colour and then use what's left as an overlay.
Your best bet would be to start by painting one of the engines that has a paintkit, like the GP38, or any of the britkits vehicles which have a painting kit; once you have an example of how overlays work, you have a head start on making your own.
