In this paper, a fast re-coloring method with information preserving is proposed for the color-blind (CB) who experiences difficulty to discriminate some color differences. In the proposed algorithm, we utilize a new color transform that can enhance the perceptibility for the CB while maintaining the re-colored image as natural as possible for the normal viewer. In addition, an improved method which effectively detects the CB unperceivable (CBU) colors to be re-colored is introduced. Experimental results show that the proposed method can produce more comprehensible images for CB viewers while preserving the naturalness of the recolored images for standard viewers with reduced complexity.
