Abstract Solid pigments not only endow rich colors to decorative ultra-high performance concrete(UHPC) but also influence its fundamental properties. In this work, three solid pigments—yellow iron oxide (Y), green iron oxide (G), and blue iron oxide (B)—were selected to investigate their effects on the fundamental properties and coloration of decorative UHPC at various dosages. The results indicate that Y, as a pure inorganic pigment, has minimal impact on the fundamental properties of UHPC. In contrast, the B and G pigments, which contain phthalocyanine, affect the workability of UHPC in different degrees. The paste became unworkable when the content of B reached 5%, and the influence of G on workability is between that of Y and B. In terms of mechanical properties, the compressive strengths of the groups with 2% B and 5% G content are reduced to 62.3% and 66.5% of the control group, respectively. Their porosity increased by 96.6% and 114.7%, respectively compared to the control group, which also led to a significant increase in the capillary water absorption coefficient. In addition, each pigment significantly changes the color of decorative UHPC at very low content (0.5wt%), Among them, Y has the most significant coloring effect, but the color change amplitude decreases when the content exceeds 0.5wt%. The type of pigment does not change the early color evolution law of decorative UHPC, and 7 d can be considered the earliest age to evaluate whether decorative UHPC color meets the design expectation or not.
