Now I always use to prime my stuff black but are certain colors better painted on if you prime white instead of black? like is black more for darker colors or can be used for everything? and white used for lighter colors?

Is thier really a difference?

 

I use gray for lighter colors, black for darker ones.

 

yes lighter colours such as yellow wont take to black. a white primer would make it really pop and take to it better!

also a silver base coat could be used for transparent colours for example to create candy colour effects.
