Holographic
A foil hue sweep over the pattern's own shading.
Holographic recolours every element with an iridescent sweep that shifts with depth and with a slowly circling view point, like a foil card tilting in your hand. It keeps each element's lightness, so the pattern's shading survives.

Cost and low power
Free: it only recolours. There's nothing to shed, so it isn't sheddable (and disable: ["holographic"] is an error that says so).
speed is turns per second of the sweep, in real time. Strokes sweep colour along their length.
Props
A foil hue sweep over each element's own lightness. In an FX Spec: /materials/holographic. Off until holographic.strength is above 0.
| Prop | FX Spec | Type | Range | Default | Description |
|---|---|---|---|---|---|
holographic.depth | /materials/holographic/depth | number | 0–1 fraction | 0.5 | Weight of the depth term (near vs far dots). |
holographic.facing | /materials/holographic/facing | number | 0–1 fraction | 0.5 | Weight of the facing term (the tilting-card sheen). |
holographic.hue | /materials/holographic/hue | number | 0–360 deg | 180 | Starting hue of the sweep. |
holographic.saturation | /materials/holographic/saturation | number | 0–1 fraction | 0.7 | Saturation the sweep blends toward. |
holographic.span | /materials/holographic/span | number | 0–720 deg | 300 | Degrees of the colour wheel the sweep covers. |
holographic.speed | /materials/holographic/speed | number | -4–4 turns/s | 0.05 | Turns per second of the hue drift and view point. |
holographic.strength | /materials/holographic/strength | number | 0–1 fraction | 0 | Amount of the foil hue sweep; 0 turns it off. |
