64 Chevy Dash Color?

[tomfg]

I'll soon need to decide on what color to paint my 64 1/2 ton. Right now, it's all white exterior, with a desert beige (closest I see listed on the paint chips), or tan interior.... dash, floor, ceiling, etc. I'm planning on painting the exterior some shade of green, but not necessary an original 1964 Green color.
Question: How many different interior colors did Chevy use in 64 besides the desert beige? Does anyone have a Green truck with a beige interior? Color coordination aint my bag, but do want a nice interior / exterior combination.
Question: What kind of paint should I use for the interior? Single stage?
I'm planning on using base coat / clear coat on the outside. Question: How in the world does one go about painting the inside of the roof? Not sure that my gun will work in that position. 64 Interior photos would be great if you have any color other than desert beige. Thanks, Tom
