This paper proposed the approach based on fractal coding which falls in the lossy compression category. Fractal coding is generally used for grey level images. Proposed method firstly separate the three planes of RGB color space images and then the fractal coding algorithm is applied on individual planes independently. Extensive experiments are carried out with different size of domain blocks and range blocks on well-known color space images from literature. Results are analyzed with respect to the time, image compression ratio and image reconstruction quality. Implementation results shows that the greater compression ration can be achieved with large domain blocks but more trade off in image quality. Results are compared and represented with the performance graph. The proposed method can be useful for the huge database applications where the image reconstruction quality does not matter much. Time complexity of the proposed method is in the order of n2 .
