The brushes referred to are part of the dialog class and were created when the dialog constructor was called.

Override the OnDrawItem() method for your CDialog derived class using Class Wizard and add the following code, changing variable names as neccessary. It is important to note that a pointer to a CDC object from the handle of the DC passed in via the LPDRAWITEMSTRUCT is required, otherwise only the background of the text will be the desired color. 

        #define RED     RGB(255,0,0)
        #define YELLOW  RGB(255,255,0)
        #define MAGENTA RGB(255,0,255)
        #define WHITE   RGB(255,255,255)
        #define BLUE    RGB(0,0,255)

          if (pTabCtrl->m_hWnd == lpdis->hwndItem)
