Do it yourself

If you go to Home Depot or similar, you will be able to locate concrete colorant, or grout colorant, either of which should work. (Read the label to be sure.) I have also heard of people using latex paint to color concrete (mixing it in). And the grandfather of a friend of mine used to mix in *food coloring*, of all things, to color his concrete projects! (He made little garden gnomes and bird baths.) BTW, a search at Google for "concrete colorant" turned up all kinds of links! If they don't have the color you want locally, I'm sure you could mail order it. Luck! Ann
