Document

Converts the components of a color, as specified by the default RGB model, to an equivalent set of values for hue, saturation, and brightness that are the three components of the HSB model.

Usage

From source file:Main.java

public static void main() {
    int red = 23;
    int green = 66;
    int blue = 99;

    float[] hsb = Color.RGBtoHSB(red, green, blue, null);
    float hue = hsb[0];
    float saturation = hsb[1];
    float brightness = hsb[2];
