'Declaration Public ReadOnly Property LuminanceModulation As System.Nullable(Of Double)
public System.Nullable<double> LuminanceModulation {get;}
Luminance is also referred to as brightness.
This property specifies the amount by which the luminance of the associated base color is increased. For example, a value of .5 yields a 50% reduction in luminance. A value of 1.0 implies no change in luminance. A value greater than 1.0 implies an increase in luminance; for example, a value of 2.0 doubles the luminance.
Assigning a value of null to this property implies that the associated color has no specific luminance modulation.
Luminance modulation is applied by converting the base color from RGB to HSL, then multiplying the luminance channel by the value of this property, then converting back to RGB.
