Visual cryptography is a method for protecting image-based secrets that has a computation-free decoding process. Visual cryptography is a cryptographic technique which allows visual information (pictures, text, etc...) to be encrypted in such a way that the decryption can be performed by the human visual system without the aid of computers. As network technology has been greatly advanced, much information is transmitted via the Internet conveniently and rapidly. At the same time, the security issue is a crucial problem in the Palettes. In this paper proposed a visual cryptographic system using Color Palettes. In this Encryption and Decryption you can easily encrypt and decrypt text (message), so you can send emails from home or office in a safe way. The proposed method is a simple, practical and effective cryptographic system. The text information is encrypted and stored in the color Palette image. Initially user has to give the secret key in order to encrypt the text. Later, when the recipient decrypts the text, the secret key user enters is and compared with the stored color palette image. And, in case, if the secret key matches the recipient entered stored key, encrypted message will be successfully decrypted. If the recipient enters wrong key, User will get an error message "Wrong Secret Key".
