Customizing tab bar icon color when popup is displayed?

I've already been able to set the text and icon colors for the tab bar items as I see fit. White for inactive, blue for active.

However, I still run into one question: When a popover or alert view is displayed, the tab bar item icon is grayed out:

Is there a way to keep blue for this state?

Thank you for your help.

EDIT

Sorry, but my question is not duplicated. I already do all this:

self.tabBar.tintColor = COLOR_CORPORATE_BLUE;
[[UITabBarItem appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
                                                   [UIColor whiteColor], NSForegroundColorAttributeName,
                                                   nil] forState:UIControlStateNormal];
[[UITabBarItem appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
                                                   COLOR_CORPORATE_BLUE, NSForegroundColorAttributeName,
                                                   nil] forState:UIControlStateSelected];

NSUInteger i = 0;
NSString *imageName = @"";
for (UITabBarItem *item in self.tabBar.items) {
    switch (i) {
        case 0: imageName = @"home_tab_db"; break;
        case 1: imageName = @"home_tab_al"; break;
        case 2: imageName = @"home_tab_ru"; break;
        case 3: imageName = @"home_tab_da"; break;
    }

    UIImage *img = [UIImage imageNamed:imageName];
    if ([img respondsToSelector:@selector(imageWithRenderingMode:)]) {
        item.image = [img imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
    } else {
        item.image = img;
    }
    item.selectedImage = [UIImage imageNamed:[imageName stringByAppendingString:@"_active"]];

    i++;
}

      

        
        
        
      

    

However, as I already wrote, any popover, alert view, etc. will change the color of my active icon to gray.
