I meant the actual interior colors for the "two-tone" interior. It looks like GMC and Chevrolet may use the same colors but in a reverse pattern. Example: The chevrolet uses the lighter blue as the main color with the dash top, side window surrounds, steering wheel the darker blue. GMC looks to use the darker blue as the main color and dash surround and side window surrounds as well as steering wheel and column the lighter blue. It looks like quite possibly, they use the same two blues but reverse the pattern.
