ウェブデザイナーのための色彩理論：カラーパレットの抽出と使用

Color is one of the most powerful tools in web design. Understanding how to extract and use color palettes from images can elevate your designs.

Color Palette Extraction

Extracting colors from images uses algorithms like k-means clustering:

1. Sample pixels from the image

2. Group similar colors together

3. Find the average color of each group

4. Return the dominant colors

Color Harmony Rules
