Hey Scott, I know I won't be of much help... but I figured what the heck, maybe I could get people thinking.
Option 1: Take a sample to Home Depot and have them computer match some paint.
Option 2: Drive yourself crazy trying to mix a concoction of paints until you get close to the match.
Option 3: Cut the red out of the decals so the red you use on the fuselage shows through.
Option 4: Paint over the red in the decals.
Option 5: Hope somebody knows what brand and color you need.
Ok, so I need help myself. But I told you I wouldn't be of much help to you.
