Changing text color of ribbon button - c++

Question

I'm having an issue in VS2013-15 where my buttons' font colour is a shade of grey rather than black.
Here is what the buttons look like currently:
Some of the text seems to change to the desired colour when hovered over. However, some don't changed even when hovered:
Any help would be greatly appreciated. Thanks.

Answer 1

I managed to fix it using Barmak's answer. The Windows 7 theme is the problem.
To fix, you have 2 options.
Option 1
Change the theme your program uses
This is a lazy work around. Just switch your visual manager from CMFCVisualManagerWindows7 to one of the other visual managers.
Option 2
Override the OnUpdateSystemColors() function
First off you'll need a new class that inherits CMFCVisualManagerWindows7:
class Win7VM : public CMFCVisualManagerWindows7
{
};
Then you'll need to call DECLARE_DYNCREATE as the object is created dynamically at runtime.
class Win7VM : public CMFCVisualManagerWindows7
{
DECLARE_DYNCREATE(Win7VM);
};
Next, you'll need to implement the class.
class Win7VM : public CMFCVisualManagerWindows7
{
DECLARE_DYNCREATE(Win7VM)
virtual void OnUpdateSystemColors()
{
CMFCVisualManagerWindows7::OnUpdateSystemColors();
m_clrRibbonPanelCaptionText = RGB(0, 0, 0);
}
};
After that, you need to call IMPLEMENT_DYNCREATE separate to your class implementation, in global scope.
IMPLEMENT_DYNCREATE(Win7VM, CMFCVisualManagerWindows7);
Finally, we need to change our usage of CMFCVisualManagerWindows7 to that of our new class:
CMFCVisualManager::SetDefaultManager(RUNTIME_CLASS(Win7VM));
