White primer works best for covering dark walls, as it conceals deeper colors easier than other shades. It will cause pink paint to appear several shades lighter than the one you selected. If you are worried that the color of pink paint you purchased is too dark, this might be the best option. You can add layers of the pink paint to make the color a bit deeper, allowing some control over the brightness white causes. However, if you prefer the exact tint of the paint, white is not an ideal choice.
Gray primer creates a solid, even color no matter the hue of the wall it covers. Light pink painted over gray primer will have the same even and solid results. However, gray primer saps the vibrancy out of most colors painted over it. Light pink will adopt a flat tone and a slight gray tint. Adding multiple layers of paint will combat these results, but the flat appearance of the color will always subtly remain. If the paint is glossy, the flat appearance will conflict, creating an unappealing result. Gray primer is best for matte light pink paint when you desire a muted result.
Tinted primers can be any color, including one that matches the hue of paint. Pink primer will ensure the color of the paint applied over it will stay as true to its original shade as possible. It works best over light colored walls. However, no matter the wall color, pink primer typically requires two or more layers to get an even result. If you want to match the finished product to the indicated color on the can of paint most closely, use pink primer.
Selecting a color deeper than the pink paint will enrich the tone of the final shade. Red primer beneath light pink paint will darken it slightly. It works best over lightly colored walls, as deep hues will make getting an even red difficult. The enriched color of pink will lighten with multiple layers of paint, but the red tone will subtly remain. If the color of pink paint is exactly the hue you desire, avoid red primer. However, red primer is ideal for pink paint if you are worried that the color will not be vibrant or dark enough.
Before considering how the primer will affect the pink paint, you must first take the existing color of the wall into account. List the best options to cover the existing wall color. From the list, select the color of the primer based upon your desired outcome in terms of vibrancy and hue.
