Usage example

swift

// You can create colors with the convenience constructor like this:
let title = UIColor(named: .articleBody)
let footnote = UIColor(named: .articleFootnote)

// Or as an alternative, you can refer to enum instance and call .color on it:
let sameTitle = ColorName.articleBody.color
let sameFootnote = ColorName.articleFootnote.color
