Here is WM_DRAWITEM:
case WM_DRAWITEM:
        {
           
			 LPDRAWITEMSTRUCT lpDrawItemStruct = (DRAWITEMSTRUCT*)lParam;
			 switch (lpDrawItemStruct->itemAction)
			{
               	case ODA_DRAWENTIRE:
				case ODA_SELECT:
				{
					
			        int ndxColor = 0 ;
					switch (lpDrawItemStruct->CtlID)
					{
					  case  IDC_btnPantone1 : ndxColor = 0 ; break ; 
					  case  IDC_btnPantone2 : ndxColor = 1 ; break ; 
					  case  IDC_btnPantone3 : ndxColor = 2 ; break ; 
					  case  IDC_btnPantone4 : ndxColor = 3 ; break ; 
					  case  IDC_btnPantone5 : ndxColor = 4 ; break ; 
					  case  IDC_btnPantone6 : ndxColor = 5 ; break ; 
					  case  IDC_btnPantone7 : ndxColor = 6 ; break ; 
					  default : break ;
					}
					switch (lpDrawItemStruct->CtlID)
					{
					  case  IDC_btnPantone1 :  
					  case  IDC_btnPantone2 : 
					  case  IDC_btnPantone3 : 
					  case  IDC_btnPantone4 : 
					  case  IDC_btnPantone5 : 
					  case  IDC_btnPantone6 : 
					  case  IDC_btnPantone7 : 
								DrawButtonColor (ndxColor, lpDrawItemStruct) ; 
								break ;
					  default : break ;
					}
					
				  }
				default:
					return DefWindowProc (hwndDlg, msg, wParam, lParam);
				  break;
                break;
			 } 
			 return TRUE;
        }

                       case WM_CTLCOLORBTN :
			{
			      SetBkColor((HDC)wParam, RGB(0,0,255));
					return (BOOL)g_hBrush;
				
			}

it is not changing .
Or m wrong somewhere ?
