This site has a guide to various paints with examples of them actually sprayed, not just the manufacturers' colour charts. It doesn't cover every colour, just those the guy has tried out by spraying them onto white plastic spoons:

The problem with onscreen paint colours is that they never actually get displayed true to the paint colour. Personally, i much prefer this one - the Online realtime model paint conversion page.   It allows comparison with multiple brands and types of paint.
