Touch-up paint: For the 88 purple haze I found that Pure Ice name brand nail polish 542cp "No Means No" is a perfect match for the dominant purple. The fading purple is either Sally Hansen brand hard as nails nail polish 370 "No Hard Feelings" . Or L.A. colors name brand color craze nail polish cnp507 "Wisteria".
