A colored cementitious composition is provided that is composed of hydraulic cement and a liquid coloring suspension. The liquid coloring suspension for cementitious compositions contains polycarboxylate dispersant, pigment, and a polysaccharide thixotropic additive. The liquid coloring suspension has improved viscosity consistency, improved shelf-life, anti- settling and anti- sludging properties, and decreased polycarboxylate dispersant requirements. 本发明提供种由水硬水泥和液体着色悬浮液组成的着色水泥组合物。用于水泥组合物的液体着色悬浮液包含聚羧酸酯分散剂、颜料和多糖触变添加剂。液体着色悬浮液具有改进的粘度致性，改进的储存时间，抗沉降和抗污泥化性能以及降低的聚羧酸酯分散剂需求。
