```
public HSBColor(java.awt.Color rgbcolor)
```
    Creates an instance transformed from the rgb color.
    
    Parameters:
    
    rgbcolor - standard java rgb color.
- Method Detail
  - rgbToHSB
```
public static HSBColor rgbToHSB(java.awt.Color color)
```
    Inspired by float[] java.awt.Color.RGBtoHSB(int r,int g, int b, float[]hsbvals) except that algorithm is tuned
    Testing results showed about 25% speed up. Therefore the sources have become harder to understand.
    
    Parameters:
    
    color - the java.awt.Color (that follows the RGB model) and should be transformed to a color instance in the hue-saturation-luminance model.
    
    Returns:
    
    the transformed values of the RGB colors in that order: hue,saturation,brightness.
  - clone
```
public java.lang.Object clone()
```
    Clone implementation.
    Following statements are true:
    x.clone() != x x.clone().getClass() == x.getClass() x.clone().equals(x) A deep copy of this HSBColor is returned.
    
    Overrides:
    
    clone in class java.lang.Object
    
    Returns:
    
    an instance copied from this one.
  - equals
```
public boolean equals(java.lang.Object obj)
```
    Overrides:
    
    equals in class java.lang.Object
    
    See Also:
    
    Object.equals(java.lang.Object)
  - getRGBColor
```
public java.awt.Color getRGBColor()
```
    Returns the transformation of this color to the rgb color.
    
    Returns:
    
    the transformation of this color to the rgb color.
  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class java.lang.Object
