Color Index

Color Index is a tool for extracting colours from images and building custom colour palettes. You upload an image or provide a URL, and the tool pulls out the dominant colours, then organises them into usable palettes. What sets it apart is the historical and cultural context it provides for each colour; rather than just showing hex codes, you get information about what colours have meant across different cultures and time periods. This makes it useful for designers who want their colour choices to carry intentional meaning, not just visual appeal. The freemium model lets you start experimenting for free, with paid options likely enabling more advanced features or higher usage limits.
