That blue just doesn't work on the 240 - it's trashy looking to my eye. This is the exact opposite of what I am going for - but I guess that's the way taste goes. When I was saying sleek, you have to think subdued and understated. People that like 240's would say - "hey, that colour looks great on a 240". The colours I would consider are this blue, the dark grey or a burgundy. Definately richer/darker colours work best, with the odd exception of the 70's pastel colours - 240's look great in whacky 70's colours.
When I was chatting with Matt some years ago about a possible colour scheme for his old 242 - I was thinking about air force blue (dusky medium blue) in a semi-gloss with darker blue gloss graphics. That would still look cool.
The stripe colour I picked out is from a 2006 Toyota (code 1G2 - Gray Mica) and looks like this:
The metal flake is about the same as the blue and the tone range is very similar. The corners of the stripe would be filleted - I was just doing a quick tape off, not masking for paint. The wheels are already painted about the same colour they left the factory - which is a metallic silver and they are staying that colour. With the black accents it should look good.
Whenever I'm playing with an idea - especially colour - I often ask myself to come up with something completely different than what I'm thinking about, in this case no blues. What colour would the car be then? I'm drawing a blank - but a deep forest green would be great if I didn't have a black interior.
