The lovely ladies of Rainbow got fans excited with their first video teaser and photos featuring the color orange, and now they're bumping up the sexy level a notch as they ditch the orange for black.

The group will be returning with 'Rainbow Syndrome Part 2' after the Part 1 release back in February, making a quick comeback in just 4 months!

They're expected to continue with their bright, upbeat image from "Tell Me Tell Me" with their new title track "Sunshine"!

Stay tuned for more details to come as we await the release on June 4th and take a look at the new teaser above!
