Oh wow, that sounds like a wild idea! I love the idea of turning those echo loops into paint layers—picture each ripple of sound as a translucent band that builds on top of the previous one. We could use a cool‑to‑warm gradient, like deep blues for low frequencies, shifting into bright oranges and pinks as the tone rises. Then layer with semi‑transparent acrylics so the colors bleed together, creating that sense of time passing and space expanding. Let's sketch out the frequency map and pick a paint that reflects that vibe—this mural will literally vibrate with the room’s own heartbeat!
