Colour Disclaimer Colour on mobile devices and computer monitors are not 100% accurate. We are using natural pigments and materials that can vary in strength and hue from batch to batch. Although color variations are closely monitored it is a good idea to buy all pigment and plaster for a project from the same lot. If that is not possible, be sure to batch your plaster and pigment materials together to decrease these variations. With this in mind, we encourage you or your applicator to make sample boards or on-site sample walls in order for to you to approve final finish and color.
