These samples are to give you a reasonable idea of the potential colors, but we can never recreate a color perfectly due to our hand built process.
You can request specific leaf fill colors by giving us the Sherwin Williams color codes (e.g., SW 7006, Extra White). Use their ColorSnap Visualizer tools to search for colors. There may be a surcharge for colors we do not already have. The above base concrete colors are always available as fill for no charge.
