This paper provides a state of the art of watermarking techniques specifically designed for color images. It presents an overview of the color image watermarking methods and an analysis of the advantages and disadvantages of the most recent schemes. It also presents solutions and arguments supporting the idea that methods based on the HVS's sensitivity provide more robust watermarks than other ones. Furthermore, this paper treats the question of the evaluation of watermarking quality according to fidelity. Finally, based on this deep analysis, research directions in color image watermarking are suggested.
