Any really light, bright color should be fine, but white is definitely the
best for UV protection. Another question to ask yourself is if you'll be
keeping it in an enclosed hangar most of the time. If so, then it's almost a
non-issue.

In Southern California I know of EZ's that are yellow, and Dick
Rutan's in Mojave is light blue. There's a beautiful Berkut in
England that's silver.

So, yes, it can be done if you are very, very careful. But do be VERY
VERY careful. Paint a sample panel, put it out at noon on one of the
hottest days of the year. Find out how hot it gets, check that
against the epoxy you're using AND the foam core - blue styrofoam
swells up when it gets too hot. It's not a cumulative problem - 4
years at 140 degrees won't do anything bad. 30 minutes at 200 degrees
and your airplane will be scrap.
