I just added this 1967 Corona to the gallery. The seller indicated that it is Light Beige code T1262 and that the paint was original.
So as far as I can figure it for 1967 there were three similar colors:
T1262 Lily White - very light off-white
T403 Light Beige - light beige
T1123 Coliseum Beige - light sandy brown
I had to add T1262 to the chart for 1967 based in the seller's information, but I don't know what other years that color might have been available. Anybody know?
