Color correction method and device and readable storage medium

The invention provides a color correction method and device and a readable storage medium, and is applied to the technical field of image processing, and the method comprises the steps: determining K color temperature intervals; wherein the difference value between the color temperatures of any two light sources in the K color temperature intervals is smaller than a first threshold value, and each color temperature interval corresponds to at least one light source; determining the CCM of each color temperature interval according to the CCM of the light source; performing linear interpolation according to the CCM of each color temperature interval in the K color temperature intervals to obtain a final CCM; and performing color correction by using the final CCM. In the disclosure, the concept of the color temperature interval and the concept of the CCM of the color temperature interval are provided, and when a certain color temperature interval corresponds to more than one light source, the more than one light
