Returns the value at a given contrast level.
Implementation
double get(double contrastLevel) => contrastLevel <= -1.0
? low
: contrastLevel < 0.0
? MathUtils.lerp(low, normal, (contrastLevel - -1.0) / 1.0)
: contrastLevel < 0.5
? MathUtils.lerp(normal, medium, (contrastLevel - 0.0) / 0.5)
: contrastLevel < 1.0
? MathUtils.lerp(medium, high, (contrastLevel - 0.5) / 0.5)
: high;
