All black North Korean Il-10 Beast: historic photograph

I found this picture of an Il-10 Russian attack plane in North Korean colors. It appears that the engine burned during enemy action, and the author suggests that the plane was burnt. Closer inspection shows that the original color of the Il-10, overall Russian green, was covered with black paint, probably for night operations in Korea, 1950. Taken in Wonsan, 1950. Please feel free to agree or disagree with me about the color scheme and as always your comments are encouraged.
