Picking the right colored concrete can sometimes be tricky. A few things are important to remember:

• First, just like picking paint colors, remember that colors can sometimes look different when applied over a large surface or area.

• The concrete color should tie to into the scheme for the overall hardscape, landscape and architecture.

• Colored concrete is a variable product that can vary depending on a number of factors when the concrete is mixed and poured. Some color variation is normal.
• Like all things outdoors, colored concrete will fade in the sun over time.

Davis Colors has a nice website showing sample images of its various concrete colors that can help make visualization easier.
