Abstract
When the coordinates of multiple primaries are set within specific ranges in a chromaticity diagram (e.g. the CIE 1931 chromaticity diagram), the proportion of the contrast ratio of one primary to the contrast ratio of the other primary should conform to some requirements to achieve the white balance of dark-state, so as to effectively display the natural color and mitigate the color shift of low-luminance images.
