To gove you an idea of what I meant, here's a couple pics of my '61 Lincoln.. Paint is HOC Kandy Brandywine, which is a transparent red. it's over a dark metallic grey. The first shot is outside on a cloudy day and the second one is with the sun shining on it.
Here's the same colour over a silver base in the sun so you can see what a difference the base makes under a candy paint..
