Decals are on.
There are more colorful Martinsydes, but not by much. One paint scheme had a large white 'A 1' on the top wing and a black version of the same on the bottom, with white '1's on the nose. I chose this one because it was a presentation aircraft with an Australian squadron and I liked the presentation logo. It turned out to be easy enough to do with my desktop publisher, and I used it to make the serial numbers as well.
