I still know nothing about painting but I'm a little more patient and I have some 1000 grit sandpaper to smooth out mistakes, so I decided to go with something less brutal but much prettier!
Getting decent photos as always, was a chore, but you get the idea here. Going with a two toned pink look instead of two different colors was a better approach, and the gloss finish gives it a candy coating, jewel-like look that I'm way into.
I painted the Power and Open buttons the darker pink, then lightly sanded the paint off the face of the buttons so only the etched words and barely visible edges of the buttons were colored. Ended up being a pretty nice effect!
In the future I'd like to sand it smoother and put a glossy topcoat on the shell to really make it durable and bright. I'm bummed that there are still a lot of mistakes here but to the casual observer it looks pretty flawless, so I'm satisfied for now!
