Here’s an update on this one, gang. It’s partially fixed, meaning when you select red on some frames, it displays as red.
Some background: the spray can slider shifts the hue, but is affected by the brightness value of the base colors. Bikes like the Zwift Steel, Aero, and Carbon have a high brightness base value, and thus will show pink instead of deep red when the slider is in the red ranges. Fixing this issue on frames like these will take more time.
