Buttons and other UI controls are not drawn using the ForeColor. You must not set the ForeColor before you draw your button, you must set the UI Color.
In your case you will want something like:
Err err = UIColorSetTableEntry( UIObjectForeground, &fg );
static void tunerFormInit (FormPtr pForm)
{
UIColorGetTableEntryRGB( UIObjectForeground, &fg );
ControlType *pButton = getObjectPtr(pForm,tuner1Button);
UIColorSetTableEntry( UIObjectForeground, &red );
CtlDrawControl(pButton);
pButton = getObjectPtr(pForm,tuner2Button);
UIColorSetTableEntry( UIObjectForeground, &blue );
CtlDrawControl(pButton);
UIColorSetTableEntry( UIObjectForeground, &fg );
}
I haven't tested it, but it should work.
Hope it helps!
Cheers!

Like this?
static void
tunerFormInit (FormPtr pForm)
{
WinSetForeColorRGB(NULL,&fg);
ControlType *pButton = getObjectPtr(pForm,tuner1Button);
WinSetForeColorRGB(&red,NULL);
CtlDrawControl(pButton);
pButton = getObjectPtr(pForm,tuner2Button);
WinSetForeColorRGB(&blue,NULL);
CtlDrawControl(pButton);
WinSetForeColorRGB(&fg,NULL);
}
It looks like it should work, but it doesn't. Anyone have an idea why?

Ehhh... This is only needed if I want to change color when the button
is tapped, right?
