Omarchy Miasma Theme

A dark, organic Omarchy theme built around xero's canonical Miasma palette: cellar-black surfaces, pale linen text, mossy greens, rust, clay, and sickly gold.

Install

omarchy theme install https://github.com/OldJobobo/omarchy-miasma-theme

Omarchy Quattro support

Miasma includes a native Omarchy 4/Quattro path:

• colors.toml keeps the canonical Miasma ANSI palette while providing semantic Quattro roles.
• shell.toml themes the bar, controls, popups, notifications, launcher, menus, Polkit prompt, lock prompt, and image picker.
• hyprland.lua provides coordinated active/inactive gradients, blur, shadow, and Miasma animations.
• Quattro outputs cover Foot, Helix, Pi, Obsidian, VS Code, Gum, RGB keyboards, and the screen-share picker.
• preview-unlock.png and unlock.png provide the theme-picker and unlock presentation assets.

The committed terminal files are intentional: they preserve Miasma's exact ANSI white and bright-black slots where Omarchy's semantic aliases favor UI text roles.

Legacy compatibility

The theme retains coherent Omarchy 3.8-era surfaces for users who still load them:

• hyprland.conf and hyprlock.conf
• waybar.css and the optional waybar-theme/ variant
• walker.css, mako.ini, and swayosd.css
• wofi.css

Additional integrations

• Terminals: Alacritty, Foot, Kitty, Ghostty, and Warp
• Editors and tools: Neovim, Helix, VS Code, Pi, btop, Fish, fzf, Gum, and cava
• Apps: GTK, Chromium, Firefox, Obsidian, Steam, and Vencord
• Aether overrides for supported Aether workflows

Neovim

neovim.lua loads OldJobobo/miasma.nvim, the maintained Miasma plugin used by this theme, and selects the miasma colorscheme in LazyVim.
