Brian I am just finishing up a 1/6 Emcor, I got the match for the yellow with the help of Gary Grembowski from out west. The original yellow was a custom mix of (3) PPG concept tints, I had Endura color match an original swatch from Gary, and then sent the Endura samples to him. He confirmed that the CLR40510 was identical. Any questions shoot me a PM.. Tony J
