Paesthetic
Paesthetic is when your colors look like they were picked by a kid who got glitter in their eyes and a crayon in their mouth.
That painting? It's paesthetic. My kid had a meltdown and a crayon.
That wallpaper? It's paesthetic. It looks like a crayon exploded in a glitter factory.
That mural is paesthetic. My sister did it while high on glitter and glitter only.
