Do I need a primer for this color?
Some colors, especially yellows, reds and oranges, and other dark accent colors, are considered to be “poor hiding” colors. That means they usually need a primer because, despite their strong, vibrant color, they’re not good at hiding the color they’re covering.
Using a grey (under dark colors) or tinted (under light colors) primer can help you avoid having to apply multiple coats of paint. A tinted primer helps prepare the existing surface for color. You’ll typically only need to apply two coats of paint over tinted primer to get that perfect result. ECOS colors that benefit from additional coats or a tinted primer are marked in our color library (select Fan Deck View) with a roller icon

Please note: this guidance is specifically related to color selection. We recommend using one of our primers if painting over a higher gloss finish, a darker color, or applying an accent color, or if applying over bare or heavily sanded surfaces.
