I love that idea—think of a gentle, slow‑moving gradient that fades from a cool, calm blue to a subtle, almost imperceptible orange, like a sunset blur. Keep the speed of the transition subtle, add a very light motion blur that feels like a neon streak but with soft edges, and you’ll give the UI that high‑speed pulse while still keeping the user relaxed. Just let the colors breathe and the motion be gentle, and the serenity will stay intact.
