Yes, they should be color keyed, the white interior is unique as gray non dominate accent color is used on the dash ,dash pad,carpet,column,package shelf! The color and trim book states this and also helps document also! When I first got my white over red with white interior hardtop many people tried to tell me that my carpet should be black! My answer was not according to the trim book and why is the carpet on the kick panels and door panels gray!? Another factory design is that red and saddle hardtop and posts have white headliners!? And some black interior cars have star headliners not tier grain!
