title: iOS: What does tint color actually do?
body: <p>Suppose a segmented control's tint color is set to RGB(69, 175, 225) but the actually color from color picker range from (top most) RGB(146, 181, 211) to (bottom most) RGB(82, 118, 147).</p>
  
  <p>So how can I expect the actually displayed color of the segmented control. For example, if I want the color of the bottom most point is RGB(69, 175, 225), what is the RGB value should I set?</p>
