The "Basic Metals" backgrounds have a rugged, industrial, and weathered aesthetic. The textures appear aged and oxidized, giving off a distressed metal look with a mix of dark, earthy tones like gray, brown, and black.
 
The blending of colors and soft yet uneven transitions suggest a grunge-inspired, almost abstract metallic finish, making them ideal for projects that require a vintage, dystopian, or raw industrial feel.
