## What is Light Noise?

The world is loud. Sometimes you need sound — and light — to tune it out.

Light Noise pairs eight colors of algorithmically generated noise with visuals that respond to what you hear. No loops. No recordings. No two moments the same.

VISUALS THAT BREATHE

Soft light responds to sound in real time. Gradients shift and glow as audio plays — something to watch while your mind settles, or ignore completely. No other noise app does this.

EIGHT COLORS OF NOISE

White — full spectrum, even and bright
Pink — softer, like steady rainfall
Brown — deep and rolling, the internet's favorite
Green — mid-range, warm and natural
Grey — psychoacoustically balanced
Blue — airy, high-frequency texture
Violet — bright and energizing
Deep Brown — ultra-low, rumbling calm

Each generated by algorithm — no samples, no loops, no repetition.
