Cam16 class final
CAM16, a color appearance model. Colors are not just defined by their hex code, but rather, a hex code and viewing conditions.
CAM16 instances also have coordinates in the CAM16-UCS space, called J*, a*, b*, or jstar, astar, bstar in code. CAM16-UCS is included in the CAM16 specification, and should be used when measuring distances between colors.
In traditional color spaces, a color can be identified solely by the observer's measurement of the color. Color appearance models such as CAM16 also use information about the environment where the color was observed, known as the viewing conditions.
For example, white under the traditional assumption of a midday sun white point is accurately measured as a slightly chromatic blue by CAM16. (roughly, hue 203, chroma 3, lightness 100)

Methods
-
distance(
Cam16 other) → double - CAM16 instances also have coordinates in the CAM16-UCS space, called J*, a*, b*, or jstar, astar, bstar in code. CAM16-UCS is included in the CAM16 specification, and is used to measure distances between colors.
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
toInt(
) → int - ARGB representation of the color. Assumes the color was viewed in default viewing conditions, which are near-identical to the default viewing conditions for sRGB.
-
toString(

A string representation of this object.
override
-
viewed(
ViewingConditions viewingConditions) → int - ARGB representation of the color, in defined viewing conditions.
-
xyzInViewingConditions(
ViewingConditions viewingConditions) → List< double>
Operators
-
operator ==(
Object other) → bool -
