Navigation bar title font colour not being set using RGB but okay with standard colours

This works. It sets the font and the colour correctly:

[self.navigationController.navigationBar setTitleTextAttributes:
 [NSDictionary dictionaryWithObjectsAndKeys:
  COA_TITLE_FONT(17.0),
  NSFontAttributeName, [UIColor brownColor], NSForegroundColorAttributeName, nil]];

This makes the title go white - or at least that's what it looks like against a coloured background:

[self.navigationController.navigationBar setTitleTextAttributes:
 [NSDictionary dictionaryWithObjectsAndKeys:
  COA_TITLE_FONT(17.0),
  NSFontAttributeName, [UIColor colorWithRed:62.0f green:116.0f blue:140.0f alpha:1.0f], NSForegroundColorAttributeName, nil]];

I use the RGB extensively in IB to set labels, buttons, etc., but can't set this one that way. I wonder if it is somehow getting a wrong tint colour, but the brown colour looks... well, brown.

You need to use decimal values for RGB. Divide all your floats by 255.0. Right now you're essentially setting it to pure white, as it just reads your >1 values as 1.0f

[self.navigationController.navigationBar setTitleTextAttributes:
 [NSDictionary dictionaryWithObjectsAndKeys:
  COA_TITLE_FONT(17.0),
   NSFontAttributeName, [UIColor colorWithRed:62.0f/255.0f green:116.0f/255.0f blue:140.0f/255.0f alpha:1.0f], NSForegroundColorAttributeName, nil]];
