I’m open to all paint schemes. Metallics are nice. I have always opted for black primarily, it just draws me in. Although, future color considerations for my next sports car would be purple, orange, blue, ect. The red on your Miata has a Nice tone. ( I really like the new crimson red on the 2018 Mustang as a secondary color.)
The one fail-safe color for me if undecided is white. To me, nothing looks better than a clean white car with a nice set of wheels. See
@SandboxGeneral new MKZ for a great example of This.
