The above colors have been diamond ground to our standard finish.  Expect final color, color field variation (water marks, casting marks, fibers, aggregate shadows) and shade (lightness-darkness) to vary in most instances. All concrete exhibits variations from cast to cast, therefore samples should be used as a general guideline only when selecting color. Color matches cannot be guaranteed. Custom colors , grinds, and aggregate  substitutions, such as recycled glass,  are available as custom colors and can be developed for any  of our fabricated concrete products.
