#411RGB Light Mixing

Three soft spotlights in near-pure red, green and blue drift on gentle lissajous orbits across a black stage. Where two overlap the additive sum blooms into cyan, magenta or yellow; where all three cross, a clean white hot-spot forms and then slides apart again. Each lamp carries a tight core and a wide halo so the colour fields feel volumetric rather than flat. Hover to grab and drag the nearest lamp, press to pump the output, scroll to widen or tighten the beams.
