1. A pigment composed of particles comprising a calcium-titanium composite oxide as a main component, wherein a lattice constant a of the pigment is in a range of 5.4700 Å or more and 5.5100 Å or less,
wherein, when the pigment is measured in X-ray diffractometry, and when a height of a diffraction line of a (1 2 1) plane appearing in a range of a diffraction angle of 32.50° or more and 33.50° or less is defined as 100.0, a height of a diffraction line of a (2 0 2) plane appearing in a range of a diffraction angle of 46.75° or more and 47.75° or less is 50.0 or less.
