A color space converter (100) is disclosed. The color space converter includes an input data MUX (110), a first and second look-up table (LUT) (104 and 106), an arithmetic logic unit (ALU) (108), and an output MUX (112). In a standard indexed color look-up mode, indexed pixel data are coupled to the LUTs (104 and 106) each of which provides direct color data to the output MUX (112). Depending upon a control signal, the output MUX (112) couples one of the direct color lines to an output. In a color conversion mode, the LUTs (104 and 106) store conversion constants. Input pixel data of a first color space format is coupled to the LUTs (104 and 106) and the ALU (108). The resulting conversion constants output from the LUTs (104 and 106) are added with portions of the input pixel data in the ALU (108) to generate direct color data of a second color space format.
