It can be pretty hard to match faded colors. For smaller touchup try mixing to match by hand. I have become a bit of a whiz at it by spraying different colors into a spay can lid. Looks like it would be best to tape off decals and repaint this one. That makes matching easier! Schwinn decals should be covered with clear coat first as tape can pul them off. I have used grease as a masking on some real delicate decals.
