Abstract: The present application provides a multiple primary color conversion method, including: determining color triangles according to color coordinates of a target color; computing grayscale components of l primary colors corresponding to the target color in the color triangles; in step S130, obtaining initial grayscales of l primary colors; in step S140, judging whether there is an overflow grayscale; if yes, then performing step S160, if no, then performing step S150; in step S150, adjusting initial brightness components corresponding to grayscale components of the same primary color as the overflow grayscale, computing grayscale components of l primary colors in color triangles including the primary color of the overflow grayscale, and performing steps S130 and S140; in step S160, determining the initial grayscales of l primary colors as grayscales of l primary colors of the target color.
