When it comes to coverage, not all paint colors are created equally. All colors have varying degrees of opacity or transparency, which determines the way it reflects light.
Opaque colors tend to obscure the surface color, while transparent colors tend to allow the surface to show through. Bright colors, including yellows, oranges, reds and primary colors, tend to be more transparent in nature. Using a gray or tinted (to the paint color) primer with these colors helps to create an ideal balance of light absorption and reflection, which in turn provides superior hide for these bold, vivid hues.

Priming is recommended to enhance coverage, adhesion and durability of the topcoat. Surfaces that should be primed include:
All unpainted surfaces (such as bare wood, plaster or new drywall)
Patched or repaired areas
Surfaces painted with oil-based paint
Surfaces that will have an extreme color change (light to dark or dark to light)
After priming interior walls or other surfaces, painting should be done within twelve hours for best adhesion.
