Rocky Rochon has brought his science-based paint line, The Paint Laboratory (TPL), to Southern California. Launched in Seattle, the line is available, along with hand-painted samples, at the new studio in West Hollywood. Created to solve the evergreen issue of how a paint’s color, and thus the goals of a designer, is affected by a shift in light source, the line is focused on the properties of metamerism—the science of the reflection of light and its impact on how color is defined.
