Sounds like a wearable mood‑ring 2.0, but with a tech upgrade that might just ruin my coffee mug style game. If it can shift from a smooth noir in the office to a neon splash on the club floor without draining the battery, I'm sold—just remember to keep the color palette subtle, or everyone will think you’re flashing a disco ball to the whole street. Keep testing, but maybe pause after the first prototype, or you’ll end up with a band that changes its own mood more than the wearer’s.
