OK, so GOUT has over-represented reds. Challenge accepted!
Enter YellowMagic™ (a joke on Laserman's BlackMagic and _,,,^..^,,,_'s WhiteMagic).
I'm not claiming that these colors are correct, but I believe this may be right approach to de-emphasizing the reds in GOUT.
gout = gout.Tweak(cont=1.1, sat=1.3).ConvertToRGB24(matrix="Rec601")
gout.Overlay(gout.BlankClip(color=$D29628), mask=gout.ShowRed(), opacity=0.1, mode="lighten")
The $D29628 color was chosen because (1) it's yellowish, (2) it's close to -1's crawl text color, and (3) I didn't know what else to choose.
Pay close attention to skin-tones. Also, note how high I'm setting the saturation. This approach works for even higher saturation values.
