A system and method for recoloring color objects selectively applies color processing operations in a particular pipelined sequence to offer improved performance and quality of color processing. The recoloring sequence includes a transformation by a 5x5 matrix that handles various types of transformations in the color space of the color object, a gamma correction, a bi-level thresholding operation, and a conversion into a color space, such as the CMYK space, for an output device. Each of these operations in the recoloring sequence may be selectively activated or deactivated depending on the attributes of the color object being processed and the desired recoloring effects. The transformation with the 5x5 matrix allows various transformation operations, such as rotation, scaling, translation, shearing, and perspective in the color space of the color object to be combined and performed in a single step, resulting in significantly improved processing efficiency.
