The old Lucas/British wiring color scheme was quite logical, up to a
point. Modern cars tend to be a nightmare, with different
manufacturers using different colours for different things, or lots of
the same color for different things, or bastard ideas like one wire of
one colour that dissapears into the loom, with a hidden joint half-way
down and emerges as two completely different coloured wires at the
other end.
This is a pretty good guide to old British wiring colours, but it is
by no means the definitive - some of the colours are not what I've
found on old cars, but you have to start with something.

As for lots of wires of different colours, when I made my loom I
re-used old wire from half a dozen (modern) vehicle looms, thus
avoiding the need to go out and buy 100 different reels of cable. The
other alternative is to mark the colour codes using different coloured
cable ties - Maplins do a pot of 1000 little ties in 10 colours which
i make much use of when sorting out wiring on old vehicles where the
wires are all black with age and dirt

And only a fiver.
