Adding a dropper selection tool

Hi there, is it possible to add a dropper selection tool to choose color anywhere on the page? Has this been done before using this plugin?

No files, tests, or entry points are named. Start by reviewing the repository's existing React color-picker components and determine whether a dropper can select a color anywhere on the page. Done would require a defined implementation scope and confirmation that the requested page-wide color selection works.
