The favorite colors of 1950 were Grey, Green and Blue – very common for the 50s. Overall, 17 exterior colors were available for the Roadmaster series. Two-Tone paint was at extra cost and limited to certain color combinations. In this case, only the roof could be painted differently. Note: Color accuracy varies by computer/device settings and depends on the actual light.
