Rather than painting the dash and bezels, I think I would try to find some grey fabric that is close to the same color as your stripes, and recover those door inserts. No way to know how it would look, but I think it was stupid that GM put so many different things, and then made them all blend by making them the same color. There needs to be some contrast. Don't go overboard, but a little can make it look right. Blue fabric on a blue door panel is too boring, but it's also not exactly invisible, so it stands out, but not really. Get what I'm saying?
For example, I have a grey interior. I'm planning on trying to find dark grey fabric to match that charcoal color in the section by the gauges, just to flow with the interior color scheme, but it would still be subtle. Hoping it almost looks like it came that way.
Then again, I'll be honest and say that there aren't many painted interiors that I like. They either do too little, so it looks out of place, or they do too much and it looks like you're sitting in an extension of the exterior. I think the interior can be different than body color, and still be made to look good on its own. Make sense?
