Christian from the local steampunk community made some color simulations.
Quite useful, I think.
Better than paint it first and hate it afterwards.
He also suggested to change the grille from oval to a horseshoe shaped one.
Now it looks more like a Bugatti or Morgan, than a Jag.
My wife just giggled, when she saw the photo, so I have to go for it.

The curved windshield is also suggested by him, but the real one will be a bit higher.
Bordeaux is now our favourite color
Bugatti blue is on second place
British racing green would be another option (for one of the next builds...)
I'm still thinking about a 2 tone scheme, all colors above can be combined with creme white.
