color-changing light, possibly an LED or decorative light, cycling through different colors. The light starts with blue, then transitions to green, then purple, and back to blue. The light source appears to be circular and surrounded by a flat, possibly tiled surface. A thin cable is visible running across the surface. The video is shot from a slightly angled perspective, looking down at the light.
