Automated color correction

A computer program product comprising:

• a non-transitory computer readable storage medium;
• program instructions for executing, by a processor, a method for correcting color of elements rendered as visual display output of a computing device, the method comprising:
• in each of a plurality of iterations, processing a visual element of a digital content container comprising a plurality of visual elements for rendition, the visual element comprising at least a foreground and background portions for which a foreground and background display color values are defined respectively, said processing comprising:
• responsive to an expected contrast ratio exceeding a contrast ratio calculated as a function of the foreground and background display color values, performing:
• determining, in relation to the expected contrast ratio and based on the background display color value, an expected foreground luminance value for the foreground portion and a substitute foreground luminance value as a function thereof;
• obtaining at least one foreground chromaticity value by converting the foreground display color value into a multi-dimensional chromatic valence color space;
• obtaining an updated foreground display color value by inversely converting the substitute foreground luminance value and the at least one foreground chromaticity value;
• and,
• responsive to the expected contrast ratio not exceeding an updated contrast ratio calculated as a function of the background and updated foreground display color values, providing an output of the updated foreground display color value.
