That pale yellow always looked great to me; could be remembering my older bro's 1st car '65 GTO in that shade of yellow. It 'pops' (just my opin). My '70 Cuda vert (yellow/black) was too yellow for my taste. I changed the color of my '63 Fury from white to gray and glad I did. My brother talked me into selecting a diff color for it last minute at the body shop and have gotten many compliments on it I think mostly to do with the striking contrast with the red stripe. LOL, the book 50 Shades of Gray...I got color chips from the shop...in the area of 150 shades! Go figure, 1st one I picked, after going through ALL of them was the choice and a Chrysler color. Changed the white vert top to black with the new color. My choices were more limited with the red insides. Anyway, back on your question...if it was me, I'd keep the yellow drumming up a marketing pitch for your son. It will be a standout at the shows.
