Maroon interior as an option for interior trim?
What year and what type of Chevrolet truck?
I do not see many pre-1954 interior options, and the pre-1953 deluxe interior RPO does mention color differences for carboard panels or arm rests?
My 1954 Suburban has maroon door panels and arm rests (standard color) - they were brown in 1953 or earlier Suburbans. Panels, Suburbans, and regular cab A-D trucks had different color panels/arm-rests - maybe brown, black, maroon?
Nonetheless, use whatever color combo suits your tastes, and suits the interior color you choose.
