Tint will never show the same color on Q-cell. You may try to darken it a bit but getting even with the color of the foam around is best made with an airbrush (AND A VERY GOOD EYE AND GOOD LIGHTNING.) Not worth the trouble, IMHO.
Balsa is right. But sometimes you cam make them less noticeable. Have you got a closeup. Let’s see how bad they are. You learned something. A shaped blank that you intend to tint must be screened as perfect as you can get it. No scratches, holes, tears along the stringer or filler.
