init(hue:saturation:brightness:opacity:)

Declaration

init(hue: Double, saturation: Double, brightness: Double, opacity: Double = 1)

Parameters

• hue:

  A value in the range 0 to 1 that maps to an angle from 0° to 360° to represent a shade on the color wheel.

• saturation:

  A value in the range 0 to 1 that indicates how strongly the hue affects the color. A value of 0 removes the effect of the hue, resulting in gray. As the value increases, the hue becomes more prominent.

• brightness:

  A value in the range 0 to 1 that indicates how bright a color is. A value of 0 results in black, regardless of the other components. The color lightens as you increase this component.

• opacity:

  An optional degree of opacity, given in the range 0 to 1. A value of 0 means 100% transparency, while a value of 1 means 100% opacity. The default is 1.

Discussion

This initializer creates a constant color that doesn’t change based on context. For example, it doesn’t have distinct light and dark appearances, unlike various system-defined colors, or a color that you load from an Asset Catalog with init(_:bundle:).
