I like mostly like muted ,dull and dark colours but I won't mind some neon or the occasional pastel.
I like electronic music of any kind.
I like things like video games(I'm a fan of Nintendo), anime, drawing(both digital and traditional).
I like clothes like jackets ,ripped jeans, sneaks and leather boots.
I don't if this helps but I really like things like stars, neon signs glitchy looking things.
This is probably really bad but it's the best I can thing of😅.
