Color variation is a characteristic of aluminum composite panels with brushed aluminum and metallic paint finishes, and can vary on material purchased from different lots. In addition, grain direction of brushed aluminum and metallic paint finishes must be considered in the design of the panel installation. Opposing grain directions may create visible patterns and may not be acceptable in the finished project. Laminators does not warrant a color match for these panels.

Sand Beige has a low-gloss finish; Matte Black has a matte finish.
