Abstract: According to an aspect, a color conversion device includes a signal processing unit and a signal output unit. When a color specified in a predetermined color space by color data based on input signals is a color outside a defined color gamut defined in the color space, the signal processing unit generates in-defined-gamut data, and when the color specified in the color space by the color data based on the input signals is a color on a border of or inside the defined color gamut, the signal processing unit does not convert the color data based on the input signals into color data of a color different from that specified by the color data based on the input signals, and generates in-defined-gamut data identical to the color data based on the input signals, and. The signal processing unit generates output signals based on the in-defined-gamut data.
