Orphist Colour Discs
The Disc, Breathing
9 concentric rings of 6 arc segments rotate in alternating directions and pulse opacity in a slow breathing rhythm, cycling a 6-color spectrum.

When to use it
Art-themed hero backgrounds, music visualizer stills, calm ambient loops on dark-mode landing pages.
When not to
Light-background UIs (background hardcoded dark navy). Contexts requiring text legibility over the disc center.
Working with an AI agent
Every component ships agent-ready metadata. An example instruction for this one:
Change RINGS to 12, slow the breath cycle by setting the multiplier from 0.8 to 0.4, and swap SPECTRUM to warm earth tones. Theme: dark tokens live in :root, the light variant in :root[data-theme="light"]; ?theme=light or a {type:'forever:theme'} postMessage switches at runtime.
Safe to edit
- ring count (RINGS=9)
- segment count (SEG=6)
- spectrum palette (SPECTRUM array)
- breath speed (t*0.8)
- rotation speed per ring (0.06+ri*0.015)
- disc radius ratio (0.46)
- theme tokens (:root dark defaults + [data-theme=light] overrides)
Keep intact
- DPR-aware fitCanvas()
- visibilitychange pause/resume
- prefers-reduced-motion static frame guard
- IIFE wrapper
- theme hook (?theme= bootstrap + forever:theme message listener + theme tokens)
Known limitations
- Background color hardcoded in both CSS and canvas fillRect — must change both to recolor
- Centre dot color cycles on floor(t) causing a sharp jump each second
More Orphist Colour Discs components
- Simultaneous Disc7 concentric spectrum rings counter-rotate in alternating directions; a shimmer overlay and pulsing center dot evoke Orphist colour.
- Circular Rhythm26 color discs pulse with sine-wave rhythm via radial gradients on a dark canvas; additive blending creates luminous overlaps in the Orphist palette.
- Prismatic Window20 colored rectangular planes in a 5x4 grid breathe, skew, and pulse opacity in staggered sine waves over a dark background, evoking Orphist window planes.
- Colour Wheel Pulse36-segment spectral disc spins while an energy crest sweeps its segments, causing slices to pulse outward and flare bright as the wave passes.
- Endless RhythmA horizontal band of split half-disc circles in spectral colors marches endlessly left in a seamless CSS loop, inspired by Orphist's rhythm motifs.
- Contrast PairsThree split circles rotate complementary halves against each other — red/green, blue/orange, violet/yellow — enacting Orphist's simultaneous contrast law.
