I set a `UIColor` using rgb to a background of a `UILabel`. I'm trying to adjust the `alpha` only. How can I modify the alpha of an existing rgb `UIColor`?
**Edit**
Basically I have `UILabels` that have a set `UIColor` (using rgb), and I won't know what color the `UILabels` are. At a certain point, I will have to change the `labels` alpha`. How can I just change the labels color alpha?
