However, colors shown may vary from actual hues and should only be used as a guide. Refer to actual product samples for final color selection. Because concrete units are manufactured with high quality, naturally-mined aggregates and materials, variations in color or shading should be expected in products that are manufactured at different times and in units having different shapes. This color or shading variation is acceptable in the industry. To Top
