What affects cement color?
A few factors contribute to the discoloration of concrete. The biggest reasons why concrete changes color are calcium chloride, water, installation methods and the overall mix of your concrete. A low water to cement ratio affects the hydration of the cement which creates a darker color.
What determines the color of concrete?
The quantity of water used in a mix controls to a large degree the durability, strength and water tightness of a concrete product. The higher the water content of the mix, the lighter the color. Control of the water/cement ratio is vital for consistent color from batch to batch.
Why is some concrete Brown and some GREY?

The degree and extent of the coloration depends on the rate of oxidation, the percentage of slag used, curing conditions and the porosity of the concrete surfaces.
