A pigment composition in which an ester compound ordinarily used as a solvent and in other applications, such as butyl acetate or oleyl acetate, is used as a flowability improver for a pigment dispersion and which comprises a pigment and the ester compound as essential ingredients, and a pigment dispersion obtained by dispersing the pigment composition in a solvent, etc. The dispersion is significantly improved in pigment dispersibility and flowability. When the pigment composition or pigment dispersion is used in producing a color filter, a homogeneous film having high contrast can be obtained.
