Notes

Swift only accepts values between 0.0 and 1.0 when declaring RGBA, while RGB stores values between 0 and 255. (The alpha in RGBA being between 0.0 and 1.0.) After searching Stack Overlow, I found I needed to divide the colors I selected by 255 to get the new ratio.

Fortunately, we can before that conversion right in the declaration.

Thus, my emerald green, rgba(46, 204, 113, 1.0), moved to UIColor(red: 46, green: 204, blue: 133, alpha: 1.0) before becoming UIColor(red: 46/255, green: 204/255, blue: 133/255, alpha: 1.0).
