Welcome to Pylette, the easy-to-use Python library for extracting color palettes from images!
Documentation: qtiptip.github.io/Pylette
Source code: qTipTip/Pylette
Pylette is a powerful yet user-friendly library designed to help you extract color palettes from images. Whether you're working on computer graphics, visualizations, or generative art, Pylette makes it easy to create visually appealing color sets.
Key features:
- Extract color palettes from images
- Support for various color modes (RGB, RGBa, HSV, etc.)
- Alpha channel support with transparency masking
- Random color selection from palettes
- Command-line interface for quick palette extraction
You can easily install Pylette using pip:
pip install PyletteOr if you prefer using uv:
uv add PyletteHere's how to extract a color palette from an image and work with it in Python:
from Pylette import extract_colors
palette = extract_colors(image='image.jpg', palette_size=10)
# Access colors by index
most_common_color = palette[0]
least_common_color = palette[-1]
# Get color information
print(most_common_color.rgb)
print(most_common_color.hls)
print(most_common_color.hsv)
# Display the palette, and save the image to file
palette.display(save_to_file=True)
# Or save palette image directly without displaying
palette.save(filename='my_palette', extension='png')
# Save palette's color values to CSV
palette.to_csv(filename='color_palette.csv', frequency=True)
# Pick random colors
random_color = palette.random_color(N=1, mode='uniform')
random_colors = palette.random_color(N=100, mode='frequency')This will give you a palette of 10 colors, sorted by frequency. The image is automatically resized to 256x256 pixels for faster processing. See the documentation for a complete list of available methods and attributes.
For images with transparency (PNG files with alpha channels), you can use the alpha_mask_threshold parameter to exclude transparent or semi-transparent pixels:
from Pylette import extract_colors
# Extract colors from a transparent PNG, ignoring pixels with alpha < 128
palette = extract_colors(
image='transparent_image.png',
palette_size=10,
alpha_mask_threshold=128
)The alpha_mask_threshold parameter accepts values from 0-255, where pixels with alpha values below this threshold are excluded from color extraction.
Pylette also comes with a command-line interface for quick palette extraction:
