Is Super Saiyan Rosé Goku Black's version of the Super Saiyan Blue or his version of the original (golden) Super Saiyan? According to the Dragon Ball Wikia "Akira Toriyama's notes for the form seem to indicate that this state is simply the Super Saiyan God Super Saiyan (blue) state with pink hair."

but according to this website in spanish, there is a japanese magazine which says "Super Saiyan Rosé is the Super Saiyajin (golden) version of Black Goku"

None of the sources is an official source. Any other info states which version is the equivalent of Super Saiyan Rosé, Super Saiyan Blue or Super Saiyan (golden) ?
The answer was given recently in manga 20 and it's blue. Rose is Black's version of the super saiyan blue
