This is a really tool. I've always been meaning to create a list of all the works that use BrandColors or are derived from it. If I ever get around to doing that, I'll make sure to include this.
Creator of BC here. If you click on a brand (outside of a swatch, which will just copy the color to your clipboard), that expands the row. If there is URL the data was sourced from, a "Source URL" link will display there. Looks like Adobe was added before we were doing that, but if you expand a brand like 500px, you'll see it.
