Working out the colour for the stripe is not easy, nor its getting the thickness and location. My wife had a friend Deb Ellery who has been an arts teacher. She offered to help and suggested that I purchased a load of paint sample cards and put them together and gave me some ideas of suitable colours to go with the Green and Orange. I also painted a couple of boards in the Green and Orange to play with. Having an idea of the basics we got together and played about a bit more. Whenever we came up with a good idea we would take a picture of it. I can guarantee that you will forget what looked good. Make sure if you do this check that the camera gives the correct representation. My Samsung failed this test but the Canon camera was pretty good.
We eventually came to the conclusion that the Orange with a Metallic Teal and thinner white stripe was the way to go.
Deb is certainly not a petrol head but she was delighted with the idea of telling her kids that she was helping with the colour scheme of a GT40.
