Hallmark mascot Rainbow Brite is another character given a cartoon that was primarily aimed at girls in the 80s. The plot inevitably revolves around bringing colour and light to a dark world, or fighting a monochrome villain who hates happiness or whatever. We couldn't tell you, we were barely paying attention.
If the reboot gains a lot of adult male fans, I think they should be called "Rain-Bros."
W4B theme composed by John Croudy.
