A image-forming apparatus includes a color-conversion unit for converting a first color data value represented by a plurality of elements included in a device-independent color space into a second color data value represented by a plurality of elements included in a device-dependent color space, an image display unit for displaying a color image by combining a plurality of light beams having different intensities based on the second color data value, and a color-reproducibility determination unit for determining that a color corresponding to the first color data value is included outside a range of colors displayable by the image display unit when at least one of the elements of the second color data value converted from the first color data value by the color-conversion unit is included outside a predetermined reference range.
