The invention discloses a multi-primary-color image saving and reconstructing method and relates to image display by utilizing color mixing effects. The method includes: saving the index variable S, using recording image points to display area number, of a multi-primary-color image and a recording vector I, which includes three components, of the multi-primary-color image into storage equipment, reading the index variable S and the recording vector I from the storage equipment, selecting corresponding mapping matrix F according to the index variable S, and performing inverse mapping from the recording vector I to multi-primary-color component vector P by the transposed matrix F' of the mapping matrix F to achieve a multi-primary-color reconstructed image. By the method, the defect that a large amount of data needs to be saved by directly saving all the components of multiple primary colors in the prior art is overcome, the defect of complexity by using multi-primary-color display and using the polyhedron of m
