No, white and black concrete colors are different from typical wall paints. Architectural concrete contains natural ingredients, such as cement and sand, which affect the final shade.
White concrete usually has a slightly grayish tint.
Black concrete is more of a dark graphite than the deep, pure black that can be achieved with wall paints.
Good to know: If you care about color matching, it is worth ordering samples to see how these shades look in reality and whether they will match other elements of the interior.
