Orange Is the New Blackface

Julianne Hough had 2 black eyes last night ... and a black nose and a black forehead ... yeah, she went full blackface.

Hough was at the Casamigos Tequila party in Hollwood ... and dressed up as Crazy Eyes -- the popular character from "Orange is the New Black."

We're pretty sure Paula Deen would have been skewered if she did it. So we gotta ask ...

12:10 PT -- Julianne took to Twitter to apologize for offending anyone with the costume explaining, "It certainly was never my intention to be disrespectful or demeaning to anyone in any way."
