I have to pour a small section of driveway strip using sacks of dry

slabs the ready mix company mixes in color, lamp black or carbon black
or their modern equivalent. It's painless, just tell them you meed a
sidewalk mix.

Stop by the ready mix company and tell them you want to buy enough
pigment to color 1/4 yard of concrete and you should be good.
