Colored concrete can be an effective tool for improving visual readability in urban design projects. The present study aims to conduct a comparative study of the effect of chemical, mineral, and composite pigments on the mechanical properties of concrete, including compressive strength and slump, to utilize colored concrete in urban design and landscape. In this regard, experiments were conducted on concrete samples with chemical pigments (in red, yellow, green, and blue), composite pigments (turquoise), and mineral pigments (limonite). The results of the experiments show that adding pigments significantly affects the flowability (slump) and compressive strength of concrete. In particular, the use of chemical pigments reduces the flowability and compressive strength of concrete, with the reduction more evident at higher pigment percentages. The yellow pigment had the least negative effect on flowability and compressive strength among the colors. In contrast, limonite mineral pigment increased the compressive strength of concrete, especially at 5 and 10 % percentages.
