• Automatically extracts prominent color palettes from images.
• Provides detailed information on color, position, and population.
• Supports multiple extraction algorithms, including DBSCAN, DBSCAN++, and KMeans++.
• Supports multiple color spaces, including RGB, HSL, and LAB.
• Supports the selection of prominent colors based on multiple themes, including Vivid, Muted, Light, and Dark.
• Available as a Rust library, Wasm, and a CLI tool.

Usage

Rust

Here is an example of extracting the color palette from an image using the Rust library. See the examples directory for more examples.

use auto_palette::{ImageData, Palette};

fn main() {
  // Load the image data from the file
  let image_data = ImageData::load("tests/assets/holly-booth-hLZWGXy5akM-unsplash.jpg").unwrap();

  // Extract the color palette from the image data
  let palette: Palette<f64> = Palette::extract(&image_data).unwrap();
  println!("Extracted {} swatches", palette.len());

  // Find the 5 dominant colors in the palette and print their information
  let swatches = palette.find_swatches(5);
  for swatch in swatches {
    println!("Color: {}", swatch.color().to_hex_string());
    println!("Position: {:?}", swatch.position());
    println!("Population: {}", swatch.population());
    println!("Ratio: {}", swatch.ratio());
  }
}

CLI

Here is an example of extracting the color palette from an image using the CLI tool.

$ auto-palette path/to/your_image.jpg -n 6 -c rgb -o table
+---+--------------------+------------+------------+
| # | Color              | Position   | Population |
+---+--------------------+------------+------------+
| 1 | RGB(221, 226, 222) | (104, 96)  |       6778 |
| 2 | RGB(3, 144, 149)   | (114, 201) |       5476 |
| 3 | RGB(23, 37, 36)    | (120, 300) |       4300 |
| 4 | RGB(36, 88, 131)   | (183, 145) |       1348 |
| 5 | RGB(254, 29, 44)   | (183, 190) |        779 |
| 6 | RGB(253, 213, 116) | (25, 158)  |        567 |
