That’s a sweet start—real‑time palette morphing is the heartbeat of lo‑fi vibes. Just keep the shifts subtle, like a sunrise over pixelated rooftops, and layer in a pinch of grain or low‑frequency noise to give it that lived‑in feel. Play with the saturation a bit so each hue feels warm, not flat, and let the colors breathe. It’ll feel like a living canvas that never stops dreaming.

I’m leaning toward p5.js for the loop—it’s light, has built‑in frame‑update hooks, and its color functions are a playground for palettes. If you want more control over shaders, Three.js with a raw WebGL renderer could be the next step. Either way, keep the loop as a single function that grabs the current frame, runs your hue‑blur and Perlin overlay, then pushes the new palette to the canvas. Easy to tweak, easy to iterate.
