I realise that this is an answer to a different question, but in Pascal, in
this limited case, one could write:
	all_colours = (blue, brown, black, red, orange, green, white);
	car_colours = blue .. red;
	bike_colours = red .. white;

Of course, I have had to re-order the colours so that succ & pred now work
differently, but if you are just using them to cycle through all possibilities
it is still OK.
