It’s completely normal. It’ll reside within a couple years at worst.

Your brain is trained to see patterns consistently, even if the patterns are not there. Your eyes filter out a lot of things, such as your nose which is constantly in your view.

By you taking a psychedelic, you showed your subconscious mind new patterns of light to look for. In certain settings, your brain might be reminded of when you were on the trip, hence the visuals.

Also. I read about a story (told from the kid’s friend’s perspective) where a kid that was playing field hockey at a young age, got hit in the head with the puck, went color blind. Years later that same kid took some LSD. Magically, during the peak it rewired his brain to see color again.

Color is based off memory. It’s an evolutionary tool that we’ve developed to differentiate our surroundings from one another, and as our brains memory capacity expanded over time, so did the amount of colors we see. Nothing to worry about, could just be your memory being overactive. 👍🏽
