Colleen Ballinger Not in Blackface in Viral Video, Wore Green 'Wicked -

A recent viral video accusing Colleen Ballinger of wearing blackface and performing "Single Ladies" has it all wrong ... and new footage lays out exactly what happened.

The clip shot back in 2009, made rounds Wednesday ... showing the popular Youtuber and two men performing the Beyoncé classic. Ballinger appeared to be in blackface during the number ... and was slammed on social media as a racist.

However, new video -- obtained by TMZ -- shows a different perspective. Prior to "Single Ladies," Colleen performed a song from the musical "Wicked" with Oliver Tompsett, one of the musical's stars.

COLLEEN IN GREEN

Colleen wore green face paint for the tune with Tompsett -- like the Wicked Witch of the West -- and went into "Single Ladies" immediately after the song wrapped.

THE CONTROVERSIAL CLIP

The sequence of back-to-back songs left zero time for Colleen to wipe off the green paint, resulting in the now-viral video accusing her of wearing blackface for "Single Ladies."

As we reported ... Colleen's under fire for what many have considered inappropriate behavior toward minors as well as racism.

She issued a 10-minute "apology" video while playing a ukulele ... a video that felt flat for a lot of people considering she didn't take ownership for much.
