the blue would look good I think. Might even consider trying a test patch and polishing it out to see how that looks.
You can do mattes and satins in single step or 2 step by using a base color and a satin or matte clear coat. I suspect if you want to buff it out for a sheen like mine you would have to do a single stage (I dunno if a matte/satin clear coat would buff up or not). Single stages are cheaper anyway.
The whole flat/satin craze has brought a new level to the paints - you can check out House of Kolor for instance and they have a whole line of "flatz" and so forth - you know something is "played out" when z's start showing up in the name
- but they certainly have a huge variety of paints available to do the satin look!
I dig the look of flats and satins. When I was a kid in the 70s and 80s I would paint cars flat and semi colors and then clear coat them, etc. and is why I always wanted to do something like that with a car. I did have my first car in primer back in the 80s but that is a real bear to keep up - recent within a couple years a guy had a primer 911 in Excellence and discussed how he maintained the look - I think he washed the car with scotchbrite or something but can't recall for sure. Takes the primer down a bit each time you wash it tho'.
