I am trying to get a color to show up on screen just like the charging battery (shown here):

After looking at the Apple Documentation on UIColor here, I have attempted using both colorWithHue:saturation:brightness:aplha: and colorWithRed:green:blue:alpha: to get a color to show up like that.

For example when I use colorWithHue:.3 saturation:.84 brightness:1 alpha:.5 on a black background, it renders a color like this:

myGreen with colorWithHue:saturation:brightness:alpha:

or the colorWithRed:0 green:1 blue:0 alpha:.5 on a black background shows up like this:

myGreen with colorWithRed:green:blue:alpha:

It doesn't have that translucent or glossy look to it.

Is there a better method to use? Or do I just not have the values right? (I have tried many combinations)

How do I define constant values of UIColor?

I want to do something like this, but I cannot get a cooperative syntax. static const UIColor *colorNavbar = [UIColor colorWithRed: 197.0/255.0 green: 169.0/255.0 blue: 140.0/255.0 alpha: 1.0]; I suppose that I could define macros, but they are ugly. >>> More
