We're in full compliance on complete RV color compliance and coordination:
Our Class C coach box is white fiberglass with medium blue graphics. All water hoses are white to match the fiberglass. The automatic step carpet is blue to match the graphics. The coach batteries' case color is blue to tie in with the step carpet and graphics. The black tank emptying hose is, well, brown .... to match the you-know-what. However, we came up with these outstanding color schemes and themes without outside advice. We had to make all the decisions ourselves. We could have used some outside advice from experienced professional RV'ers. :B
