Terms of the Trade: What Is Colorant?
Colorant is the dye or pigment used to tint paint. Here's a handy tip: Use colored paint as a colorant in white primer to reduce the number of coats you need. Simply mix a small amount of the colored paint into white primer. The resulting shade will be lighter than the paint, but still have primer qualities. Using primer tinted with this colorant will require less coats of paint than if the primer was plain white. While you can order primer that's already tinted, this is an easy and customizable DIY hack!
