Different squadron within the 356th FG. Each had its own rudder and spinner identifying color. The 361st was blue, 360th FS was red, and the 359th was yellow. The ground crews got pretty creative with the paint as the War was winding down in 1945.

Based on these images, it looks to me like the blue diamonds were closer to Insignia Blue than I have shown on Jersey Jerk. And thanks guys, I appreciate the good words.
