Themes

ANetBBS ships eighteen hand-picked themes, all WCAG-AA-readable on
body text:

Modern Dark (default) — high-contrast Catppuccin-style palette
Classic Green — green-on-black BBS terminal look
Amber Terminal — warm amber on dark brown
Blue Ice — cyan on deep navy
Matrix — bright neon green on pure black
Synthwave — hot pink + cyan on dark purple
Paper White — light theme for daytime
VOID SIGNAL — triple neon (green + cyan + magenta) on pure black,
with scanlines, brand glitch, and animated card borders
HACKERS (1995) — neon violet + lime + cyan rave cyberpunk, an
homage to the 1995 film
Graphite Teal — neutral graphite dark theme with a single refined
teal accent and Manrope headings, built for long reading sessions
Ivory Editorial — warm cream daytime theme with a deep
forest-teal accent and serif headlines
Retro Web '99 — tiled pinstripe background, beveled Windows-95
chrome, underlined blue/purple links, Times New Roman
Command Deck — the one theme that changes the page shape, not
just its colors: a fixed icon rail replaces the top navbar (hover to
expand, flyout submenus), mission-control blue chrome with amber
status-light badges, Sora + IBM Plex Mono. Real mobile treatment,
not a squeezed-down desktop layout: a slide-in drawer plus a
thumb-reachable bottom tab bar on phones.
Ceefax Teletext — 1980s broadcast videotext: flat primary-colour
blocks, chunky VT323 pixel type, hard right angles everywhere, no
gradients.
Brass & Oscilloscope — a ham-radio control room: brushed walnut
panels, brass rivets on the navbar and cards, oscilloscope-green LCD
readouts, Oswald + JetBrains Mono.
Mahogany Study — a gentleman's reading room: deep mahogany,
brass nameplates, leather-bound cards, Playfair Display + Lora, with
a small illuminated drop-cap on each card's opening line.
Cyanotype Blueprint — an engineering schematic: Prussian-blue
grid paper, white/cyan line-art only, dashed part boxes with corner
crosshairs, Big Shoulders Display + Space Mono.
Riso Pop-Art Arcade — a pinball backglass poster: flat saturated
red/blue/yellow on black ink, thick comic outlines with hard offset
shadows, Anton + Archivo.

Per-user

Profile → Themes lets the user pick. Choice is sticky.

Custom themes

Admin → Themes has a builder where the sysop picks colors with
hex pickers. The full set of CSS custom properties:

--theme-bg            page background
--theme-bg-dark       darker bg (cards, modals)
--theme-primary       accent / borders
--theme-primary-dark  hover / active accent
--theme-text          body text
--theme-text-muted    secondary labels
--theme-card-bg       card surface
--theme-input-bg      form fields
--theme-input-focus   focused field
--theme-border        misc borders

The theme builder writes all 10 so you don't need to touch CSS.
