Color Palette Extractor
指导
Color Palette Extractor
Upload any image and instantly extract its dominant color palette. Uses median cut quantization to identify the most prominent colors, giving you accurate HEX, RGB, and HSL values with usage percentages.
如何使用
Upload an image by dragging and dropping or clicking the upload area. The tool automatically analyzes the image and extracts the dominant colors. Adjust the number of colors to extract, then copy individual color values or export the entire palette.

- Multiple color formats – Get values in HEX, RGB, and HSL
- Usage percentages – See how prominent each color is in the image
- Palette export – Export as CSS variables, JSON, SCSS, or download as a PNG swatch
- Adjustable palette size – Extract anywhere from 2 to 12 colors
- 客户端处理 – Your images never leave your browser
常问问题

What is a color palette in design?
A color palette is a curated set of colors chosen to work harmoniously together in a design project. Palettes typically include primary, secondary, and accent colors along with neutrals. Good palettes consider color theory principles like complementary, analogous, and triadic relationships. Professional designers often extract palettes from photographs or nature to ensure the colors feel organic and cohesive.

How does color quantization work?
Color quantization reduces the number of distinct colors in an image to a smaller set of representative colors. Algorithms like median cut, k-means clustering, and octree quantization group similar pixels together and select the most dominant or representative color from each group. This is the same technique used in GIF compression and is the foundation of automatic palette extraction from images.

What is the difference between RGB, HSL, and HEX color formats?
RGB defines colors by mixing red, green, and blue light values (0-255 each). HEX is simply RGB written in hexadecimal notation — #FF0000 equals rgb(255,0,0). HSL describes colors by hue (0-360° on the color wheel), saturation (intensity), and lightness (brightness), which maps more intuitively to how humans think about color. Each format represents the same colors but is useful in different contexts.
