Instance Property


A formatted string that specifies the components of the color.


var stringRepresentation: String { get }


The string representation always has four components—red, green, blue, and alpha. The default value for the alpha component is 1.0. For example, this string:

@"0.5 0.7 0.3 1.0"

indicates an RGB color whose components are 50% red, 70% green, 30% blue, and 100% opaque (alpha value of 1.0).
