background color not working as expected
<p>I'm trying to apply a custom RGB color to background, but it is not displaying the intended color, instead it always shows white:</p>

<pre><code>UIColor *color = [UIColor colorWithRed:76 green:76 blue:76 alpha:1.0];
mainTable.backgroundColor       = color;
self.scrollView.backgroundColor = color;
</code></pre>

<p>however if I change one param to max eg Red:255 then I do see red color, any idea why I'm not seeing the color I'm looking for: 76 76 76 should have given some kind of dark grey color.</p>

<p>Thx</p>
