I was trying out different color palettes to see which one I preferred. The top palettes are based off the mimic octopus and the blue-ringed octopus, respectively. The rest aren't inspired by anything, I just thought the colors looked nice.

I decided to go with the mimic octopus color palette as the main one. The colors compliment each other nicely, and it doesn't look too busy as a result.
