Zombie Walk palette

A moody, urban-horror palette: #1F2937 provides a cold, nighttime slate backdrop; #3F6212 suggests mossy, shadowed vegetation creeping through cracks; #65A30D pops as sickly, radioactive green highlights and glowing eyes; #A3A3A3 offers concrete, weathered surfaces and muted midtones; #78350F injects rust, dried blood, and decayed leather warmth. Together they evoke a gritty Zombie Walk—damp alleys, biohazard glows, and tactile decay.
