Cold governs; amber only warns.

The same two axes with the roles swapped. Cyan takes the accent, so the desktop reads calm, and amber is demoted to warning and error, so the things that are wrong read hot. The quietest theme of the set, and the one built for long sessions.

It is also the only one that spends its accent on a cold colour. Every other theme here puts the warm hue in front. Pick this one if you want the desktop to stop asking for attention.

omarchy theme install https://github.com/r-bart/omarchy-periphery-theme.git
omarchy theme set periphery

Or use Install > Style > Theme in the Omarchy menu, then pick Periphery under Style > Theme (Super + Ctrl + Shift + Space).

Requires Omarchy 4. The palette uses the semantic key set, which does not exist in 2.x.

Window borders come from hyprland_active_border, which Hyprland and every shell card share. palette-check.png renders the whole palette into a simulated bar, terminal, menu and notification, if you want to judge the colour relationships without installing anything.

WCAG relative luminance, against both surfaces a theme renders text on. lighter_background is where tooltips, floats, status lines and Neovim's NormalFloat sit — the surface most palettes forget to check.

Every chromatic clears 4.5:1 on both. Body text clears 10:1.

colors.toml, icons.theme and backgrounds/. Nothing in this repository runs on your machine: no neovim.lua, no terminal config, no vscode.json.

That is a choice, not a constraint. A theme can ship those files, and Omarchy will use them: omarchy-theme-set copies the whole theme directory into the staging area, and omarchy-theme-set-templates only renders a template when the output file does not already exist, so anything the theme ships wins over the generated version. Leaving them out is what makes the entire desktop fall out of the palette, window borders included — and it is also why shell.toml is left to Omarchy's template, so this theme keeps picking up shell improvements on each release instead of pinning a snapshot.

hyprland-extra.lua is documentation, not a theme file. Omarchy loads no Hyprland config from a theme, and omarchy theme install drops it outright — see Window metrics.

Five, cycled with Super + Ctrl + Space. The same five ship with every theme in this set; only the order differs. Omarchy picks the first in sort order, unless the background you were already on shares its filename with one of these — then it advances to the next, because omarchy-theme-set cycles from the current entry.

JPEG, not WebP. Omarchy's shell is Quickshell, and a stock Omarchy 4 install has no Qt WebP decoder — qt6-imageformats is not a dependency of omarchy or quickshell, and none of the 22 built-in themes ship a .webp background. A WebP wallpaper is selected happily by omarchy-theme-set and then fails at Error decoding: ... Unsupported image format, leaving a black desktop, a blank tile in the theme switcher and blank thumbnails in the background picker.

Encoded at 2912×1632, quality 95, baseline, with no chroma subsampling. Full chroma matters here. Every scene sets a saturated warm edge against a cold field, and 4:2:0 softens that edge. macOS sips writes 4:4:4 only at quality 100, which triples the file for no visible gain. These were built with cjpeg -quality 95 -sample 1x1 -optimize.

Add your own in ~/.config/omarchy/backgrounds/periphery/ — they appear alongside these.

Not part of the theme. Omarchy never reads a Hyprland config from a theme directory; the only thing a theme sends the compositor is hyprland_active_border. To match the design, paste the block below into ~/.config/hypr/looknfeel.lua, which is loaded after both Omarchy's defaults and the active theme, so it wins over both.

Do not go looking for hyprland-extra.lua on your disk after installing. It is in this repository to be read, but omarchy theme install stages only what is colour and drops every .lua a cloned theme ships — a theme's Lua is code the compositor would run at login, and installing someone's theme should change what your desktop looks like, never what it runs. The block is reproduced here so this README stands on its own.

hl.config({
  decoration = {
    rounding_power = 4,

    -- The 0.05 gap is what marks the focused window.
    active_opacity = 0.90,
    inactive_opacity = 0.85,

    -- Translucency without blur makes text unreadable over these wallpapers.
    blur = {
      enabled = true,
      size = 6,
      passes = 2,
    },

    shadow = {
      enabled = true,
      range = 20,
      render_power = 4,
      color = "rgba(060f1299)",
      color_inactive = "rgba(060f1266)",
    },
  },
})

Omarchy 4 configures Hyprland in Lua, not .conf, and there is no ~/.config/hypr/hyprland.conf. Corner rounding is a machine-level setting that each person picks for themselves in ~/.config/hypr/looknfeel.lua, not something a theme has any say in. Omarchy ships 0; this palette is agnostic either way.

Worth knowing if you change it: the shell mirrors Hyprland's decoration:rounding into its own card corners, so rounding your windows also rounds the menu, launcher, notifications and tooltips. And it only re-reads that value on startup, on a theme change, and on the omarchy toggle window-gaps flag — a hand-edited looknfeel.lua plus hyprctl reload rounds the windows while the shell keeps the old radius until you re-apply a theme or restart it.

Same five wallpapers, different palette over them.
