I sat in the cockpit of both a MiG-17 and a MiG-19 several years ago. They wouldn't allow photographs but I remember the cockpit of both were about the same color; a decidedly coolish tone of light gray (lighter than ghost gray but darker than camouflage gray) with no hint of tanish or bluish tint at all. I must qualify my statement with the fact that these were the only ones of these marks that I've been able to get inside of. The MiG-21s were all that puky blue-green color.
