🎨 Paletted

A lightweight CLI utility for dynamic theme generation. It derives color palettes from live wallpapers or images and applies them across the system through configurable templates and appliers

How It Works

1. Extract a frame from the wallpaper (or use the image directly)
2. Generate a Material Design color palette with Matugen
3. Apply colors to templates and appliers
4. Execute configured commands and wallpaper backend

Installation

Dependencies:

• python >= 3.11
• magentum
• ffmpeg
• pipx

pipx install paletted

Main Configuration

The main configuration file contains global settings, notification options, wallpaper backends, and imported modules

# config.toml

# Include external modular configurations

[settings]
# Path to save the extracted frame preview
save_frame_to = "./wallpaper_preview.png"

[notification]
enable = true
summary = "Paletted-Themes"
text = "Theme applied. Wallpaper updated"

# Executed when the wallpaper source is a video
[[backend]]
type = "video"
exec = "smooth-slapper %wallpaper_path%"

# Executed when the wallpaper source is a static image
[[backend]]
type = "image"
exec = "smooth-slapper %wallpaper_path%"

# Target package application mapping
[[package]]
name = "hyprland"
template = "hyprland.conf.template"

applier = "hyprland"

Theme template

Colors can be referenced using placeholders and modifiers:

• {{color.modifier(factory)}}

where color is the base color, modifier is the transformation to apply, and factory is the modifier parameter

Modifiers:

.alpha(factor) -> Sets opacity (0.0 to 1.0)       | Example: {primary.alpha(0.5)}
.dark(factor)  -> Darkens the color (factor > 1)  | Example: {primary.dark(1.2)}
.light(factor) -> Lightens the color (factor > 1) | Example: {secondary.light(1.5)}
.sat(factor)   -> Modulates saturation (0.0 - 5)  | Example: {tertiary.sat(0.5)}
.rgb           -> Formats to CSS rgb/rgba string  | Example: {surface.rgb}
.strip         -> Removes the '#' prefix symbol   | Example: {error.strip}

Palette Colors:

# Primary
accent              = "{primary}"
on_accent           = "{on_primary}"
container           = "{primary_container}"
on_container        = "{on_primary_container}"

# Secondary
accent              = "{secondary}"
on_accent           = "{on_secondary}"
container           = "{secondary_container}"
on_container        = "{on_secondary_container}"

# Tertiary
accent              = "{tertiary}"
on_accent           = "{on_tertiary}"
container           = "{tertiary_container}"
on_container        = "{on_tertiary_container}"

# Surface
background          = "{background}"
on_background       = "{on_background}"
surface             = "{surface}"
on_surface          = "{on_surface}"
variant             = "{surface_variant}"
on_variant          = "{on_surface_variant}"

# Borders
outline             = "{outline}"
outline_variant     = "{outline_variant}"

# Error
accent              = "{error}"
on_accent           = "{on_error}"
container           = "{error_container}"
on_container        = "{on_error_container}"

# Inverse
surface             = "{inverse_surface}"
on_surface          = "{inverse_on_surface}"
primary             = "{inverse_primary}"

Example:

# hyprland.conf.template

$active_border_1 = {{on_secondary.strip}}  ->  313032
$active_border_2 = {{outline.strip}}       ->  929095
$inactive_border = {{surface.strip}}       ->  141314
$shadow = {{outline.strip}}                ->  929095

Custom appliers

Appliers provide a programmatic way to generate output when template-based substitution is not flexible enough

Each Applier must define a function whose name matches the file name:

# hyprland.py

def hyprland(color_parser) -> None:
  print(color_parser("primary.rgb"))

The provided color_parser callable can be used to resolve any supported color placeholder

Usage

Generate and apply a theme:

palleted apply /path/to/wallpaper/  # --source-index 0-1 --config-dir /path/to/paletted_configs/

Restore the previous wallpaper:

palleted restore  # --config-dir /path/to/paletted_configs/

Why Paletted?

Unlike static themes, Paletted automatically generates a cohesive color scheme based on your wallpaper and applies it to your entire desktop environment and applications, in accordance with templates and appliers.
