Prismatic
PRISM
PRISM is a light-mode-first design system built on a prism-glass material model: light splits into spectra at edges, shadows carry color rather than gray, and the near-white field does the work. It inverts the dark-mode / liquid-glass conventions on purpose.
The whole system is parametric. A single anchor hue (--h, in OKLCH degrees)
drives every brand color — rotate it and the palette re-derives. There are two
modes: day, and redshift (night), where night is treated as a wavelength
shift rather than a darkness (--hr = redshift(--h)), minting zero new colors.
Explore the live, interactive showcase at /design/prismatic:
drag the anchor-hue slider and toggle the mode to watch the entire page — including
hairlines, shadows, and the outline display type — recast in real time, all while
holding WCAG AA contrast across the wheel.
As of v0.7 the page is also a hologram: your pointer is the light source. Six registered custom properties on the root form a holographic reference beam, and every dichroic edge, chromatic cast, glint and tilt derives from them in pure CSS — the driver writes at most one quantized batch per frame, so the light play costs almost nothing. A companion Icons & Displays section (after Ink & Switch’s Tenfold) renders one-bit icons on tiny emissive pixel screens, including a paintable display — click and drag everywhere.
