I finished mine as the 82/83/76 scheme. That was an early 262. So I "believe" that's the correct color pattern.
Big problem is "NO ONE KNOWS FOR SURE" what the correct scheme for any 262 was. At that late in the war, records weren't kept up on that. So I say paint it to what you think the scheme should be. No one can prove you wrong.
The other pattern that I use for the Me-262 is 81/83/76. That's what I used for Bar's and Galland's jets.
Hope this helps you out, or at least gives you a start.
BTW don't look at the Osprey books to seriously, many of those profiles have been proven wrong.
