Ambience: slow fades for mood lighting

Demo: faster cycle to show gamut

Video: retro colour wash backdrop

Brightness: reduce in dark rooms

Heat: phones can warm at max brightness

OLED: colour motion helps, still avoid hours at max

Looks different? True Tone / Night Shift affects colour.

Banding visible? try lower brightness or slower speed.

How do I exit? ESC or tap/click anywhere.

Can I stop on a colour? press STOP (stays on last colour).

Slow cycles feel like ambient lighting; faster cycles feel like a retro shop demo.

Use the slider to find a speed that looks smooth on your device.
