A lot of aircraft paint schemes are in either the “dull but practical” or “deliberately showy” category. Then you have one of my personal favorites, used briefly by Moldova for MiG-29s.
This Fulcrum, in the process of being shipped to the US as part of a purchase deal, has a very green color scheme. A lot of Soviet-era aircraft have a “ground color on top to help camouflage when viewed from above and blue underneath to help when viewed from below” paint scheme. This has a dark green on top and light, seafoam green on the bottom color.
MiG-29s have displayed some very interesting color schemes over the years, and there’s a site that has chronicled them with excellent illustrations. I like interesting footnotes like this.
