Owner, 2026-10-19: full color-scheme support for the viewer, the top Neovim-style schemes, about twenty families each with a flyout of all its variants, a light/dark/all filter, Ayu included, alphabetical, a whole row to click. - The sidebar's corner button (the light/dark toggle before) opens the menu: the filter, then, alphabetically and all on screen at once (in columns in a short window), Ayu, Catppuccin, Cyberdream, Dracula, Everforest, GitHub, Gruvbox, Kanagawa, Material, Melange, Monokai Pro, Night Owl, Nightfox, Nord, One Dark, Oxocarbon, Rosé Pine, Solarized, Sonokai, Tokyo Night and Wanderbooks (the viewer's own Light and Dark): 80 schemes, each variant a row with a strip of its colors. - Colors from each scheme's official source, checked value by value (docs/color-schemes.md; the table names the sources). - Every palette, the viewer's own included, keeps every text color (figures, gains and losses, warnings, links, secondary and faint text) at WCAG AA (4.5:1) on every ground it sits on, soft fills included; a color that falls short keeps its hue and only changes lightness. Text, secondary and faint text stay apart (each 1.2 times the next), gains, losses and text and the charts' series shown together stay plainly different (CIE76 ΔE 20). - The scheme sets both egui styles and pins its mode, so the system turning light or dark changes nothing (it made figures unreadable). - Preferences now live in the platform's place for app settings ($XDG_CONFIG_HOME/wanderbooks-viewer on Linux), not eframe's default, which was $XDG_DATA_HOME/wanderbooks: the data root's own place. The old file is moved once. - Tests: every page of thirteen painted in all 80 schemes, the same words in the same places, each text readable on what was painted under it; the menu's order, reach and whole-row clicks in a tall and a short window; the system flip; preferences restored. Two review rounds. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01T3gXMVt7XJPi6ens1or9Dj

# Color schemes in the viewer
|
|
|
|
The viewer's color-scheme menu (the button in the sidebar's lower corner)
|
|
offers its own scheme, Wanderbooks Light and Dark, and twenty families of
|
|
popular editor schemes, each with all its variants: 80 schemes in all (78
|
|
and the viewer's own two). The menu's filter narrows the list to light or
|
|
dark schemes. Families are listed alphabetically, each one's variants too,
|
|
in as many columns as the window's height needs, so every family is on
|
|
screen at once; a variant's whole row (its colors and its name) chooses
|
|
it.
|
|
The choice is a viewer preference, kept with eframe's other preferences;
|
|
nothing is written to the books, and no figure or word changes with the
|
|
scheme (`schemes.rs`, `painted`).
|
|
|
|
Owner, 2026-10-19: "full blown colorscheme support … all the top neovim
|
|
style colorschemes"; "on the order of 20 families, each with a flyout of all
|
|
its variants"; a light/dark/all filter; Ayu included.
|
|
|
|
## Where the colors come from
|
|
|
|
Each scheme's sixteen colors (`crates/ledger-gui/src/schemes/table.rs`) were
|
|
taken from its official source and checked value by value (2026-10-19); the
|
|
table names the source above each family:
|
|
|
|
| Column | What it is |
|
|
|---|---|
|
|
| bg | the editor background (Normal) |
|
|
| dim | a panel or sidebar background (mantle, bg_dark, bg0 …) |
|
|
| raised | a raised surface (surface0, bg_highlight, float …); recorded, not used |
|
|
| sel | the visual-selection background; recorded, not used |
|
|
| border | the split or border color; recorded, not used |
|
|
| fg | the text (Normal) |
|
|
| muted | secondary text (subtext, fg_dark, subtle …) |
|
|
| faint | comments |
|
|
| accent | the scheme's signature accent: in most its blue; Ayu's yellow-orange, Dracula's purple, Rosé Pine's iris, Monokai Pro's yellow, Material's teal, Nord's frost cyan (nord8), GitHub's own accent blue |
|
|
| red, green, yellow, orange, blue, purple, cyan | its named colors |
|
|
|
|
Where a scheme has no color for a column, the closest official one stands
|
|
in (Dracula has no blue: its ANSI blue, its purple; Sonokai has no cyan: its
|
|
blue; Oxocarbon has no yellow: IBM Carbon's, and no orange: its pink). A few
|
|
columns repeat another for the same reason: seven schemes have one
|
|
background (Gruvbox Dark Hard, Nord, Solarized Dark and Light, Cyberdream
|
|
Dark and Light, Melange Dark), dim being their bg. Variant names are the plugins' own (GitHub
|
|
Dark Default, not Dark, which is another theme).
|
|
|
|
## How the viewer paints with them
|
|
|
|
- The page is the darker of a scheme's bg and dim, the cards the lighter,
|
|
so cards stand out in light and dark schemes alike. A scheme with one
|
|
background gets a second a shade toward its text: lighter cards in a
|
|
dark scheme, a darker page in a light one.
|
|
- Secondary text is the scheme's muted color, unless that is no dimmer than
|
|
its text (Nord's documented "subtle" tone is brighter): then a tone
|
|
between its text and its comments.
|
|
- Selection is the cards tinted with the accent; the new-entry highlight is
|
|
the cards lightly tinted with the yellow (at 10%: a stronger tint left
|
|
too little room for colored amounts on it, and bleached Nord's red to a
|
|
pink).
|
|
- The charts' series are the scheme's blue, cyan, yellow, purple, orange,
|
|
green, red and accent, in that order, each that looks like one already
|
|
taken (CIE76 ΔE under 20) passed over: Monokai Pro and Sonokai name their
|
|
cyan with their blue, and Kanagawa Dragon's blues, cyans and purples are
|
|
near one another. The three the charts show together (net, income,
|
|
spending) are always plainly different.
|
|
- **Readable, always.** Every color that carries text or a figure (text,
|
|
secondary text, the faintest text, which carries chart amounts and entry
|
|
numbers, gains, losses, warnings, links) reaches WCAG AA contrast (4.5:1)
|
|
on every background it is drawn on: page, cards, sidebar, hover,
|
|
selection, the new-entry highlight, and the soft fills of pills and
|
|
badges. A scheme's color that falls short keeps its hue and saturation
|
|
and only gets lighter (dark schemes) or darker (light ones), just far
|
|
enough. Gains, losses and plain text stay plainly different to the eye
|
|
(ΔE 20 or more apart). egui's own faint text (placeholders) is the
|
|
secondary text; the logo's initial is black or white, whichever reads on
|
|
the accent. The viewer's own palettes go through the same rule (it lifted
|
|
Wanderbooks Light's green on the sidebar from 4.35:1, its faint text and
|
|
warnings too, and Wanderbooks Dark's faint text).
|
|
- **Three levels of text, always apart.** Lifted one by one, secondary and
|
|
faint text came out alike (identical in some schemes, faint above
|
|
secondary in others). So the faintest is lifted first, then secondary
|
|
text until it reads at least 1.2 times better than the faint on the
|
|
ground it reads worst on, then the text the same over secondary.
|
|
- The scheme sets both of egui's styles and pins its light or dark theme,
|
|
so the system turning light or dark later changes nothing.
