I did not see it was set to 0, I must have accidentally set it before. Either way, set it to 1 and it still randomizes colours instead of setting the saved colour 
I didn’t know you could save colours like that! Thanks 
Still having the same issue… can’t figure out why still. Thanks all for helping still!
Edit
Actually that does give me a clue. Alpha controls opacity right? So logically if it was correctly saving and loading primary (which was set to 0 Alpha) then the loaded colours should have been invisible for Primary specifically. But they weren’t which means it’s not loading the saved colours. Hmm…
Actually nvm, I’m only saving the 3 colours now that I look at it. Alpha wasn’t being saved in my vector. So that shouldn’t have affected anything.
