I belive that it was Inverted Rainbow. Here's why: Yesterday, when they went into White's room they noticed that some of the books from the bookshelf were missing, including a book called "how to make a table" that had a knife in it. She most likley put the knife in there so she knew which one to read later. She read this book explaining how to properly set a table, so that she could sabotage something at the dinner table to get her next victim. Also, today she was talking with the chef, most likley asking him/her about how they set up the table so that she knew exactly what to do. Along with this, she probably thought as she was reading the book about the bookshelf that was in Red's room, and how she could use it to potentially kill him. That's why I think it was Inverted Rainbow.

But, hopefully that fottage of him getting killed allowed Red to get 100 subs.

uh, orange, he's wearing white on his hands (i don't think i can guess myself, that's why my response is so bad)

I think Artic did it, and here's why:

Artic wants to save Antartica, right? It's pretty cold, so you would need gloves. Also, it didn't specify what Type of gloves were found. It only says "White Gloves"

Let me explain this murder:
So, Artic's first murder was a success! White is now dead! He decided to go to a pool party with friends and plan.
When Red left with his camera, he left after him.
Once Artic and Red were upstairs, Artic went into his room to grab his Gloves and make his murder.
He also went into Skyangel's room to grab a Doctor's Mask to try and frame him later.
However, Red had accidentaly left his camera on, but it wasn't very good, which WAS good for Artic.
Then, once Red was downstairs, Artic hid behind his Bookshelf, and was ready for him to come.
Once Red had come into his room, he wanted to grab a book off his shelf, but then Artic shoved the Bookcase down, crushing Red in a puddle of blood and books.
Then, Artic took off his Gloves and tossed them in the bin on his way out, and he also put Skyangel's Mask into his room.
The camera had caught all of this, but no color was there.
But what could that camera reveal?
