Add a color picker (eye dropper tool) in color selection pane
This is very useful when composing a slide and wanting to match a color from an imported image, for example.

Right now you can only drag around and use in browser color pickers, it would be great to have the option to insert a HEX or RGB color code https://krogerfeedback.bid/
This is in particular useful for any subreddit that has official images/color schemes.
