Tint of UIBarButtonItem doesn't match color I set
===

The background color for my view in RGB format is 
R:  111/255
G:  209/255
B:  229/255

I tried setting the tint of the UIBarButtonItem using:

    CGFloat nRed=111.0/255.0;
    CGFloat nGreen=209.0/255.0;
    CGFloat nBlue=229/255.0;
    UIColor *myColor=[[UIColor alloc]initWithRed:nRed green:nBlue blue:nGreen alpha:1];
    [[UIBarButtonItem appearance] setTintColor:myColor];

The color does change for all the UIBarButtonItems I have in the project...but it is still noticeably different from the color of my background.  Any thoughts?
