Can you have too many different colors/lack of a color scheme?

I apologize that I’m only posting small parts of the room, because the living area is quite messy and we have plans to organize more in the next couple weeks. The large paintings will be hung over the sofa soon. I bought and found a lot of decor that I liked, in colors I liked, over the past year, without really considering the colors in the big art pieces (it was easy to forget because it’s taken us so long to put them up). Every accent color in the room repeats at least once (one main shade of green, pink, yellow, multiple shades of blue that each repeat) but I’m realizing there’s no predominating color – just a lot of different colors splashed here and there. I definitely didn’t follow the 60-30-10 rule. I would appreciate any thoughts. I can also repost this once the place comes together more.
