Seems we have the same map, although mine was produced in the UK by Collins
in Association with Rand McNally. But anyway, looking at other Rand McNally
state maps they all seem to use the same colour scheme that you describe.

As with most countries you find different colour schemes used by different
map producers. For instance, a couple of other CA/SF maps I have show:

Hertz (Produced by Colour-Art Inc) uses:
Freeways: Dark Green with black casing
Tolled: Yellow with black casing
Other 4 lane divided highways. Thin red
Everything else: Thin grey

H.M. Gousha uses:
Freeways: Bluish red with black casing
Tolled: Bluish red with black casing
Other 4 lane divided highways. Orange with black casing
Everything else: Thick black (thin black in urban areas)
