Unlike automotive paint, which is mixed to a specific color or paint code, our parts feature multiple layers of up to 12 different colors in each unique design.  We cannot guarantee color matching to factory or custom motorcycle paint, as color accuracy isn't guaranteed. Due to the coloring process, in certain bright lighting conditions a metamerism may occur which may make some colors appear an altered shade or more vibrant than usual.
