Ah when I first skimmed this I thought it was about making our brand colors available.
Now I see you're looking for tools that can analyze a website and extract a color palette based on the colors used in that site. Here are some tools that can do this:
- Web Colour Data: This web service finds out which colors are used on a given web page. You simply submit a URL, and the service auto-extracts and analyzes the colors on that pageā
- Color Palette Generator: This tool allows you to enter the URL of an image to get a color palette that matches the image. It's useful for developing a website color scheme that matches a stock photo or a specific webpageā
- Pictaculous: Although primarily used for generating a color palette from PNG, JPG, or GIF images, you can potentially use this tool with images from a website to get their color palettesā
