From what I've been able to determine, the cockpit interior is RLM 66 gray (I use ModelMaster European 1 dark gray); the rest of the interior was anodized metal, roughly the same goldish color as the inside of a soup can. I've been using Model Master jet exhaust. Wheel wells and panel insides of most German planes were RLM 02 light gray-green, but I've read that the 262 wasn't, relying only on the anodizing. Of course, I could be wrong :D.
