Get GroupBox text color (colour)

[H-S]

Can anyone help.
I have a C# app developped in C# Express. I have a form which contains
several groupboxs, with text labels.
I also have a standard "label" on the form. I want to set the label
colour to be the same as the groupbox labels.

I can't find a way of reading the group box's text font colour. (Maybe
it is something to do with a theme?)

Surely this should be easy, but I can't find a solution.

//Label is called "pPanelLabel."
//If I have a group box called "fred"
pPanelLabel.Font = fred.Font;
pPanelLabel.ForeColor = fred.ForeColor;
//Above does not affect font colour.
pPanelLabel.ForeColor = Color.Fuchsia;
//Above line colours label pink.
