Custom Color Option: Use of eyedropper feature

It would be very helpful to add a feature to the custom color selection to use the "eyedropper" as it can be used in MS office applications and most other standard applications. It would enhance the opportunity to match color schemes without having to identify the HEX color code e.g. # FFFFFF. The eyedropper lets you point anywhere on your screen to a color to your liking and automatically turns your selected visual to that color code.
