Orphist Colour Discs

Contrast Pairs

Three split circles rotate complementary halves against each other — red/green, blue/orange, violet/yellow — enacting Orphist's simultaneous contrast law.

When to use it

Art/design portfolio heroes, color-theory explainers, ambient dark-mode backgrounds where rhythmic geometric motion is desired.

When not to

Light-background layouts (background hardcoded #0c0d11). Contexts where slow looping geometry feels too abstract.

Working with an AI agent

Every component ships agent-ready metadata. An example instruction for this one:

Add a fourth pair by appending [PAL.blue, PAL.yellow] to the PAIRS array; the cellW math auto-adjusts since it divides W by cols. 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

  • color pairs (PAIRS array)
  • rotation speed multiplier (0.5+i*0.25)
  • circle radius ratio (0.40)
  • divider line opacity pulse (0.4+0.4*Math.abs(...))
  • background color (#0c0d11)
  • theme tokens (:root dark defaults + [data-theme=light] overrides)

Keep intact

  • REDUCED prefers-reduced-motion guard (static frame fallback)
  • visibilitychange pause/resume
  • DPR-aware fitCanvas with setTransform
  • IIFE wrapper
  • theme hook (?theme= bootstrap + forever:theme message listener + theme tokens)

Known limitations

  • Background color hardcoded in both CSS and canvas fill — must change both to retheme
  • No touch/pointer interactivity — purely passive
  • Pair count drives column width automatically but PAL only defines 7 named colors

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.
  • Sun & Moon DiscsTwo large radial-gradient discs — a warm sun and cool moon — orbit the canvas center in opposite phase, blending with 'lighter' compositing where they…
