In the present paper, we propose lossless compression for RGB color still images which consist of three planes, though many of the proposed techniques for lossless compression are for gray scale images. In the proposed method, we realize effective coding by modifying the prediction errors obtained from each plane. We use color space correlation in modification of prediction errors. High speed and effective context modeling in entropy coding is also realized using prediction errors of previously coded pixels around the pixel being encoded.
