Bat Cave palette

A brooding, subterranean palette evoking a Bat Cave: an almost-black midnight base anchors deep navy stone, with steel-blue stalactites and worn granite highlights. Striking electric violet suggests bioluminescent fungus or neon reflections, while warm amber provides torchlike contrast and focal energy. Use the dark tones for immersive backgrounds and mood, the steel blue for texture and depth, violet as a vivid accent, and amber sparingly to draw attention and warm the composition.
