Abstract
The invention relates to assessing the level of visual contrast between foreground and background in visually presented information, and more particularly, to a method and apparatus for determining whether a given set of foreground and background colors creates sufficient visual contrast to ensure legibility for the general population, as well as for individuals with visual disabilities, including color blindness/deficiency.
Claims11
A method of providing an objective evaluation of the legibility of color selections for foreground content and background of visual displays, in terms of the presentation of adequate visual contrast, comprising the steps of:
- (a) receiving as input a foreground color for the foreground content and a background color for the background;
- (b) calculating the visual contrast between the foreground and background colors;
- (c) displaying the results of the calculation of the visual contrast of the inputted foreground and background colors in the form of an objective evaluation of the legibility of the inputted color combination.
