Word 2007 cell color doesn't show in Shading menu

[RNW]

Using Word 2007 in Compatibility mode.

In my table, I've got a cell filled, say, blue. It's a custom color and I
want to see what the RGB values are so I can use it somewhere else. So I go
to table tools \design \ shading \ more colors, and it shows that the cell is
filled with black. When I go back and try it again later, it shows the
correct blue.

I'm not insane and I'm really good with Word so I don't really think this is
user error. And it's happened many times to me since switching to 2007.

Anyone else having this problem? Is it a compatibility mode issue?

Thanks.
