Abstract: An information processing apparatus (10) for evaluating the chromatic discriminability of content includes: a unit (S12) that converts the color space values of each of first and second verification points A and B on the content into Lab color space values; a unit (S13) that calculates the color difference and the lightness difference between the first and second verification points based on the Lab color space values; and a unit (S23, S24) that determines color-difference discriminability by comparing the color difference between the first and second verification points with a color-difference threshold, and determines lightness-difference discriminability by comparing the lightness difference between the first and second verification points with a lightness-difference threshold.

Abstract: A program provides a color palette which is provided as a plug-in for content creation software as a user interface to cause a computer to implement means for determining color difference identifiability of other colors with respect to a specified color specified by a user among a plurality of colors provided in a plurality of color parts that constitute the color palette for each of the non-handicapped, the color vision handicapped and the elderly, means for determining brightness difference identifiability of other colors with respect to the specified color among the plurality of colors for each of the non-handicapped, the color vision handicapped and the elderly, means for identifying a color group for which the non-handicapped or the like are commonly provided with identifiability for color differences and brightness differences based on the color difference identifiability and the brightness difference identifiability and means for switching a display mode of each of the color parts between a user specif
