Frostveil

A dark Omarchy theme built around a single ice accent on a cool, almost-black base. The colour follows a strict lightness ramp (the philosophy of Solitude): grey-blue slots climb in luminance in clear steps, two slots carry real ice colour, and the bottom of the desktop stays dark so text always reads first. The active window border carries a gradient that fades through slate to the background at the centre of the edge, so windows read as lit at the corners and dim in the middle.

Palette

colors.toml defines the sixteen color0–color15 slots; the named tokens (red, green, yellow, blue, magenta, cyan) and their bright_ counterparts are resolved from them by Omarchy. Note that orange resolves to the same value as yellow (#d1e1e9): the ramp has no separate orange slot, and templates that ask for orange get the pale yellow.

The 16-colour ANSI ramp is defined in colors.toml and is what terminals, btop and the shell all read, so editing colors.toml updates the whole desktop. Every bright_* slot is genuinely lighter than its regular_* counterpart so that bold text and TUI key hints stay legible, and no two of the sixteen slots share a value, so neighbouring hues can never collapse into each other.

Lightness is not monotonic across color0–color7, and that is deliberate. color3 (yellow) is the lightest slot in the normal range at Y≈0.73, because yellow reads as a highlight when it is pale; the ramp then steps back down to color4 (blue, Y≈0.37) before rising again through magenta and cyan to color7. So color4–color7 is a strictly increasing run, and color1–color3 is another, with the yellow peak between them. Sorting the ramp by lightness rather than by slot index is what keeps a TUI's "brightest" colours from sitting in the middle of the scale. Neovim is generated from the same ramp, see Neovim below.

Two ice blues

Frostveil carries two accent blues. The accent token is the deep ice #2c7190: it is what app buttons read (omawrite, for example, paints its primary button with the theme's accent and hardcodes white text), and white on #2c7190 clears WCAG AA (5.42:1). The bright ice #6bcee5 is reserved for surfaces that sit on the dark background, where it is the selection tint, the polkit glyph, the launcher/menu selected text and the notification countdown. The shell sections that must keep bright ice — [bar], [notifications], [menu], [launcher], [polkit], [lock] and [image-picker] — are pinned through shell..toml overrides, which Omarchy merges into the generated shell.toml at theme-set time.

btop needs the same split, and for the same reason. Omarchy derives btop.theme from colors.toml, but its own history says not to: the PR that introduced the templates (4a07b94) reads "Bring back explicit btop themes — they're too involved to derive from a basic color set", which is why lumon, retro-82, last-horizon and solitude all ship their own. Derived, the selected row resolves selected_fg = {{ accent }} on selected_bg = {{ selection }}, i.e. #2c7190 on #2b4663 — 1.79:1, the worst of the 22 themes Omarchy ships. So btop.theme is shipped here, and it is the generated file verbatim apart from the selection pair, which uses the selection_background / selection_foreground tokens the template ignores: #6bcee5 behind #0e1114, 9.55:1.

gtk.css follows the same split. GTK apps get accent_bg_color = deep ice with a white label (accent_fg_color, 5.42:1), and their selection background too, since Adwaita uses one colour for both the accent fill and text selection. Accent-coloured text — links, labelled values — takes the bright ice (accent_color) instead, because it sits on the dark background rather than on the accent.

Note that the deep ice cannot carry a dark label: #0e1114 on #2c7190 is only 3.49:1, which fails AA for body text. That is the whole reason the accent is dark and paired with white.

Border gradient

The gradient lives in one field and drives both Hyprland windows and the shell's popups:

hyprland_active_border = "#8fa3b5 #3f5a70 #1a2736 #3f5a70 #8fa3b5"

Dropping the trailing deg angle gives the horizontal default. 90deg is vertical, 45deg diagonal. Note that Hyprland maps a linear gradient across the whole window box, so 45deg and 0deg skew on non-square windows; the horizontal default is the one that stays balanced across aspect ratios.

hyprland_active_border = "#8fa3b5 #3f5a70 #1a2736 #3f5a70 #8fa3b5"

The centre stops drop toward the background so the gradient visibly fades across the edge — grey-blue steel at the corners, night in the middle, in the same desaturated family as Solitude's border.

Background

backgrounds/BG2.webp is an AI-generated glacial image whose visible colour sits at hue ~241° (Nord), in the same cool family as the accent, with its lighter area at the top of the screen where little sits. It is veiled (gamma darkened to a mean luminance just above the theme background, 95% of pixels below Y 0.085) so the wallpaper never competes with either the UI accent or terminal text, and stored as WebP q82 (197 KiB) to keep the repository light.

Files

Files that omarchy theme install does not copy

Omarchy deliberately drops a few files when installing a theme from a git repository, because they can name a program to launch. These files are in the repository for you to copy by hand, but installing the theme will not put them on your machine:

Everything else — colors.toml, backgrounds/, preview.png, hyprland.conf, hyprlock.conf, the CSS files, chromium.theme, btop.theme, icons.theme and the shell..toml overrides — is installed normally and needs no manual step.

If you want the skipped ones, the instructions are below.

Neovim

Omarchy generates a Neovim spec from colors.toml on every omarchy theme set and writes it to ~/.local/state/omarchy/current/theme/neovim.lua. That spec drives aether.nvim — bg, fg, muted, selection, the full ANSI ramp and the accent — so the editor is coloured straight from this palette rather than from a second one kept in sync by hand.

Nothing installs that spec for you, because it belongs to your Neovim config. Point LazyVim at it with a symlink:

ln -sf ~/.local/state/omarchy/current/theme/neovim.lua \
        ~/.config/nvim/lua/plugins/theme.lua

The name matters. Omarchy's omarchy-theme-hotreload.lua looks for plugins.theme to re-colour the editor when you switch themes, so a symlink named anything else (an older plugins/neovim.lua, say) silently disables hot-reloading. With the symlink in place, LazyVim/LazyVim picks up colorscheme = "aether" from the spec and the editor follows the desktop.

Restart Neovim afterwards. If Aether does not appear, run :Lazy sync once.

If you prefer a colorscheme that stands apart from the UI, delete the symlink and set your own colorscheme in ~/.config/nvim/lua/plugins/ instead.

Terminals

The terminal configs are not installed automatically. Each one is a drop-in file you copy to the right place. You only need the one for the terminal you use.

foot (Omarchy's default)

foot.ini is a complete standalone config: the full Frostveil palette plus a translucent blurred background, an 11pt JetBrainsMono Nerd Font, a beam cursor and 10 000 lines of scrollback.

THEME=~/.config/omarchy/themes/frostveil
mkdir -p ~/.config/foot
cp "$THEME/foot.ini" ~/.config/foot/foot.ini
omarchy restart terminal

Because a theme-supplied foot.ini is never regenerated, editing colors.toml will no longer update foot — the palette in foot.ini is a copy. If you change the palette, mirror it in the [colors-dark] section of your foot.ini too.

Prefer to keep foot tied to the palette? Delete foot.ini from your copy of the theme. Omarchy then regenerates it from colors.toml on every omarchy theme set, and you can still get the look by adding just the presentation settings to ~/.config/foot/foot.ini:

[main]
include=~/.local/state/omarchy/toggles/foot.ini
include=~/.local/state/omarchy/current/theme/foot.ini
term=xterm-256color
font=JetBrainsMono Nerd Font:size=11
pad=14x14
initial-window-mode=windowed
workers=0

[colors-dark]
blur=yes
alpha=0.95

[scrollback]
lines=10000
multiplier=7.0

[cursor]
style=beam
blink=yes

This second form is the more flexible one: colours stay generated from colors.toml, and only the presentation is yours.

Other terminals

THEME=~/.config/omarchy/themes/frostveil

# Alacritty
mkdir -p ~/.config/alacritty && cp "$THEME/alacritty.toml" ~/.config/alacritty/

# Ghostty
mkdir -p ~/.config/ghostty && cp "$THEME/ghostty.conf"    ~/.config/ghostty/config

# Kitty
mkdir -p ~/.config/kitty && cp "$THEME/kitty.conf"        ~/.config/kitty/

# Warp
mkdir -p ~/.config/warp-terminal/themes && cp "$THEME/warp.yaml" ~/.config/warp-terminal/themes/

Look'n'feel

Omarchy does not source hyprland.conf automatically. Hyprland reads the generated hyprland.lua, which already carries the border gradient, so the theme alone gives you the palette and the border. The rest of the look'n'feel — gaps, blur, shadows, dimming, tearing — is in hyprland.conf and has to be applied by you.

The settings it carries are:

You have two ways to apply them.

Option A — source the file. Add this to the bottom of ~/.config/hypr/hyprland.lua, after the Omarchy requires:

source = (os.getenv("HOME") .. "/.config/omarchy/themes/frostveil/hyprland.conf")

Option B — copy the settings. Add them to ~/.config/hypr/looknfeel.lua, which Omarchy already loads for you. This is the tidier option because it keeps your own config self-contained:

hl.config({
  general = {
    allow_tearing = true,
    gaps_in = 4,
    gaps_out = 8,
    border_size = 2,
  },
  decoration = {
    motion_blur = { enabled = true },
    blur = {
      enabled = true,
      size = 10,
      passes = 2,
      new_optimizations = true,
    },
    shadow = {
      enabled = true,
      range = 16,
      color = "rgba(00000052)",
    },
    dim_inactive = true,
    dim_strength = 0.5,
  },
})

Then reload Hyprland:

hyprctl reload

Lock screen. hyprlock.conf only defines colours. Source it from your own hyprlock config to get a matching lock screen:

source = ~/.config/omarchy/themes/frostveil/hyprlock.conf

Install

omarchy theme install frostveil

Or from the URL directly:

omarchy theme install https://github.com/amaurisd97/omarchy-frostveil-theme.git

Then apply it:

omarchy theme set "Frostveil"
