Make it yours.

Settings & appearance

Press ⌘, for Settings. Most of what you’ll reach for lives in two places — Appearance for the look, Keyboard and Hotbar for how you drive it. Everything applies live.

The look

• Theme — pick from the built-ins (Rascal Light, dark, and several more) in Settings ▸ Appearance or View ▸ Theme, or load your own (below).
• Accent colour — recolours selection, badges, and the active-pane border on top of any theme.
• Density & font size — tighten or relax row spacing and bump the base text size for a comfier list.

Keys & chrome

• Keyboard — every command is rebindable in Settings ▸ Keyboard, with live conflict detection. The full default list is in HOTKEYS.md.
• Hotbar — curate the per-pane toolbar of one-click actions in Settings ▸ Hotbar; drop your favourite commands right where you want them.
• Chrome — hide the toolbar and title bar for a quiet, content-first window, and toggle the sidebar with ⌥⌘S.
• Vim mode — flip on modal navigation and drive with hjkl, /, dd, gg, G.

Crafting a theme

A theme is a single JSON file of hex colors. Drop it in the Themes folder and Rascal repaints every panel — list, sidebar, toolbar, path bar, and the floating finders — to match. The built-in themes are written in exactly the same format, so any of them doubles as a starting template.

The fields

Colors are #RRGGBB or #RRGGBBAA (the alpha form is handy for the translucent selectionBackground). Only id, name, and the color fields are required; the rest fall back to sensible defaults.

A complete example

A soft, warm light theme called Blossom:

{
  "id":                  "blossom",
  "name":                "Blossom",
  "appearance":          "light",
  "background":          "#FFF7FA",
  "sidebarBackground":   "#FCEDF3",
  "toolbarBackground":   "#FDF1F6",
  "pathBarBackground":   "#FCEDF3",
  "rowAlternate":        "#FBEFF4",
  "labelPrimary":        "#3A1F2B",
  "labelSecondary":      "#7A5566",
  "labelTertiary":       "#B08C9C",
  "accent":              "#E0457B",
  "selectionBackground": "#E0457B33",
  "rowHeight":           24
}

1. Save the file as blossom.json in ~/Library/Application Support/FinderTwo/Themes/ — View ▸ Theme ▸ Reveal Themes Folder opens it for you.
2. Choose View ▸ Theme ▸ Reload Themes (or relaunch).
3. Apply it from View ▸ Theme, ⌘⇧P → Theme: Blossom, or Settings ▸ Appearance.
