  • Patent number: 11302283
    Abstract: The present disclosure provides a screen color conversion method, a storage medium, and an electronic device. The method can include when an adjustment operation for a correlated color temperature of a color in a screen is triggered, determining target Red-Green-Blue (RGB) coefficients according to a relation curve between the RGB coefficients and a correlated color temperature, and a target correlated color temperature corresponding to the adjustment operation. The relation curve reflects a relation between a tristimulus value of a white color displayable for the screen and a correlated color temperature determined based on a black body radiation locus, and a target conversion matrix between the tristimulus value and the RGB coefficients. The method can further include converting the color in the screen to a target color corresponding to the target correlated color temperature according to the target RGB coefficient.
