A liquid coloring suspension for cementitious compositions is provided which contains polycarboxylate dispersant, pigment, and thixotropic additive. The liquid coloring suspension increases the color of cementitious compositions, reduces the water content and has long term stability in that it does not become increasingly viscous over time.
