A method of providing a dark viewing mode with enhanced visual contrast includes evaluating the luminance and chroma of background colors, including highlight colors, of digital content prior to converting the digital content for the dark viewing mode to identify highlight colors having a luminance value that exceeds a luminance value threshold and a chroma value that exceeds a chroma value threshold. When a highlight color has luminance and chroma values that exceed the respective threshold values, the luminance value of the highlight color is clamped to a predetermined lower luminance value before converting the value for the dark viewing mode. The luminance value is converted for dark viewing mode by taking the opposite luminance value. As a result, the luminance value of the converted highlight color has a higher luminance value and greater luminance contrast with respect to the dark background in dark viewing mode.
