VFD
A vacuum-fluorescent display: cyan-white light on near-black glass, with a glow and a ghost. Frequencies, levels, status screens.
Kit parts
LCD
A value that changes, on grey-green liquid crystal, with a ghost of the unlit segments behind it: clocks, battery, counters.

Anatomy
A span in Geist Mono with tabular figures: a grey-green fill with a glare gradient, a shadow inset at the top, and a one-pixel offset text-shadow for the gap between the segments and the back plate. The only literal colours are the display tokens: light, not paint.

Props and options
| Name | Kind | Description |
|---|---|---|
| data-ghost | attribute | The unlit segments, drawn behind the value. Same width as the value, digits as 8. |
Usage notes
Look behind the digits: the unlit segments stay faintly visible, as on the real glass.
Accessibility
- It is text: screen readers read the value and the unit. The ghost is a pseudo-element and is not read.
- Segments on glass hold above 7:1.
