摘要

A color gamut forming apparatus includes a reference color acquiring unit and a converted color gamut forming unit. The reference color acquiring unit sets at least a saturated color, which is reproducible on a contour of an input color gamut, as a reference input color and acquires a reference output color which is a color obtained by converting the input reference color into a color being reproducible in an output color gamut. The converted color gamut forming unit forms, in the output color gamut, a converted color gamut in which the reference output color corresponding to the saturated color on the contour of the input color gamut is a convex point.
