public final class Hct
extends Object

HCT, hue, chroma, and tone. A color system that provides a perceptually accurate color measurement system that can also accurately render what colors will appear as in different lighting environments.

Method Details

from

public static Hct from(double hue,
 double chroma,
 double tone)

Create an HCT color from hue, chroma, and tone.

Parameters:

hue - 0 invalid input: '<'= hue invalid input: '<' 360; invalid values are corrected.

chroma - 0 invalid input: '<'= chroma invalid input: '<' ?; Informally, colorfulness. The color returned may be lower than the requested chroma. Chroma has a different maximum for any given hue and tone.

tone - 0 invalid input: '<'= tone invalid input: '<'= 100; invalid values are corrected.

Returns:

HCT representation of a color in default viewing conditions.

fromInt

public static Hct fromInt(int argb)

Create an HCT color from a color.

Parameters:

argb - ARGB representation of a color.

Returns:

HCT representation of a color in default viewing conditions

fromFx

public static Hct fromFx(javafx.scene.paint.Color color)

getHue

public double getHue()

getChroma

public double getChroma()

getTone

public double getTone()

toInt

public int toInt()

inViewingConditions

public Hct inViewingConditions(ViewingConditions vc)

Translate a color into different ViewingConditions.

Colors change appearance. They look different with lights on versus off, the same color, as in hex code, on white looks different when on black. This is called color relativity, most famously explicated by Josef Albers in Interaction of Color.

In color science, color appearance models can account for this and calculate the appearance of a color in different settings. HCT is based on CAM16, a color appearance model, and uses it to make these calculations.

See ViewingConditions.make for parameters affecting color appearance.
