compareLuminance method
Exposure method for > operator.
Parameter returnBrighter is true by default, and so this color will
be returned if it is brighter than other. If this color is brighter
than other and returnBrighter is false, then other is returned
instead.
The matter of being "brighter" is determined by the > operator, which
compares the colors using computeLuminance.
"This value is computationally expensive to calculate."
Implementation
Color compareLuminance(Color other, {bool returnBrighter = true}) =>
this > other
? returnBrighter
? this
: other
: returnBrighter
? other
: this;
