If you want the tone to stay light and really "pop", use white or silver pearl as your base coat. Etching primer, then white or light gray primer, then base paint, then your tinted layer. You should try and stick with ONE brand of paint for the entire job, primer through clear. And any good jobber (paint supply) can custom blend your translucent color and rattle can pack it for you. Fair warning... real auto paints in rattle cans have to be used quickly, so if you go this route, buy enough of whichever layer to shoot all the parts in one session. Then do your next layer. Automotive paint will outlast whatever standard "foo foo" can brand you would normally use.
I've been an on again off again painter for a couple decades. I wouldn't use House of Kolor again if it was the only real automotive paint I could find. It sprays like water, really thin and will run before you know it, you really have to pay close attention to what you are doing if you use it. Deltron, Delthane and Imron clears are thicker and can be tinted to whatever shade you like. But are highly toxic to work with, don't spray them in your house or standard garage.
