RGB color oriented DNA based computing is a new research area in cryptography. In this paper, a formal approach to encrypt and decrypt information using colors is proposed. An information or message consists of set of characters, symbols, and digits. Encoding is done using UNICODE, so that any language can be encrypted. After encoding, the message is encrypted and compressed using RGB colors. Each color has its own hexadecimal values; these hexadecimal values are converted into binary values. These binary values are treated as 2 parts-message and the key.
