Stamped concrete is often colored using dust-on concrete color hardeners. Dry color pigments are spread over the surface of the newly poured concrete before the stamping process begins. Some of the most popular colors are Venetian Pink, Steadman Buff, Platinum Gray, Dark Red, Walnut, and Slate Gray. Decorative concrete contractors often combine these colors using different color tones on each texture pattern to create one of a kind concrete patios, pool decks, driveways, and walkways.
