JBS provides a carbon black for coloring cement excelling in dispersibility in cement slurry, exhibiting superior adhesion to a cement matrix, and excelling in coloring characteristics and strength, and a method for coloring a cement-formed product using the carbon black. The carbon black for coloring cement is a carbon black in which humic acids are adsorbed on the surface by a surface treatment using an aqueous solution in which the humic acids are dissolved. The carbon black is preferably a carbon black on which humic acids are adsorbed by wet-granulation and drying using an aqueous solution in which the humic acids are dissolved as granulation water.
