Color

public enum Color : Encodable
extension Color: CustomPlaygroundDisplayConvertible
extension Color: ExpressibleByIntegerLiteral

Data structure that stores color, optionally with opacity.

Color can be expressed in a variety of ways:

  • As a one of 100+ CSS named colors :

    let darkRed = Color.darkRed

  • As red, green and blue pixel intensities with optional alpha channel for transparency:

    let black = Color.RGB(255, 255, 255)
let blackTransparent = Color.RGB(255, 255, 255, 0.2)

  • As hue, saturation and lightness values, also with optional transparency:

    let pink = Color.HSL(300, 100, 50)
let pinkTransparent = Color.HSL(300, 100, 50, 0.3)

  • As a hexadecimal integer literal in 0xRRGGBB format:

    let black: Color = 0xffffff

Transparency is expressed as alpha channel between 0 (transparent) and 1 (opaque). Valid lightness and saturation values are percentages between 0 and 100. Hue represents a positive angle smaller than 360°. There are no checks, clippings or exceptions that enforce these constraints.

Warning

CSS hexadecimal 3-digit #RGB and 6-digit+transparency #RRGGBBAA formats are not supported. For example the following code doesn’t work as expected:

let black: Color = 0xfff // Blue #000fff
let blackTransparent: Color = 0xffffff88 // Yellow #ffff88

It’s not possible to distinguish between these situations in Swift because they are all of the same type - a hexadecimal 32-bit integer literal. Failures, tough, are usually very visible and produce a significantly different result. The only correctly working format for literals is #RRGGBB.
