Abstract
In this paper we propose a new scheme for a (2,n)-visual threshold scheme (VTS) for color images. Our scheme achieves a better color ratio than the schemes proposed by Koga et al in 1998 and 2001. The pixel expansion of our scheme is reasonably good and we also give a lower bound on the color ratio of our scheme.
