Abstract: Methods for making powder coating compositions are disclosed in which at least one first powder coating composition and at least one second powder coating composition are mixed. The at least one first powder coating composition, when deposited upon a substrate and cured, provides a cured coating having a first hue and a first L* value, and includes opaque particulates. The at least one second powder coating composition includes translucent or opaque particulates that have external colorant particles removably adhered thereto. In the methods, the mixture, when deposited upon a substrate and cured, produces a coating having an L* value within 20 units of the L* value of a coating formed from the at least one first powder coating composition alone. Also disclosed are powder coating compositions produced by the disclosed methods, powder coating systems, related kits, methods for matching a preselected hue, coated substrates, and method for coating a substrate.
