Rainbow Walker is a color-changing action game designed by Steve Coleman for the Atari 8-bit computers and published by Synapse Software in 1983. A Commodore 64 port followed. Coleman also wrote another game published by Synapse in 1983, Pharaoh's Curse.
The Atari version was later part of a "Double Play" promotion, where some Synapse games had a second, complete game on the other side of the diskette. The Double Play re-release of Rainbow Walker includes the game Countdown by Ken Rose.
