I have a problem when it comes to trying to repeat a customized color, whether it be within the document or in a new document where I would like to use this color again.

How do I know what shading or RGB code I used? There seems to be no record of it. This is always a problem, but especially with the page background color since I can't seem to be able to select and copy the color.

In both cases there is no way to know what the exact RGB code is, whether it be the page background color or shading within the document, at least not that I can find.

Is there any way to know exactly what color a customized color is so that it could be repeated elsewhere or maybe saved somehow?
