Package org.eclipse.swt.graphics
Class RGB
java.lang.Object
org.eclipse.swt.graphics.RGB
Instances of this class are descriptions of colors in terms of the primary
 additive color model (red, green and blue). A color may be described in terms
 of the relative intensities of these three primary colors. The brightness of
 each color is specified by a value in the range 0 to 255, where 0 indicates
 no color (blackness) and 255 indicates maximum intensity.
 
The hashCode() method in this class uses the values of the public fields to compute the hash value. When storing instances of the class in hashed collections, do not modify these fields after the object has been inserted.
 Application code does not need to explicitly release the resources
 managed by each instance when those instances are no longer required, and
 thus no dispose() method is provided.

Constructor Details- 
RGBpublic RGB(int red, int green, int blue) Constructs an instance of this class with the given red, green and blue values.- Parameters:
- red- the red component of the new instance
- green- the green component of the new instance
- blue- the blue component of the new instance
- Throws:
- IllegalArgumentException-- ERROR_INVALID_ARGUMENT - if the red, green or blue argument is not between 0 and 255

RGBpublic RGB(float hue, float saturation, float brightness) Constructs an instance of this class with the given hue, saturation, and brightness.- Parameters:
- hue- the hue value for the HSB color (from 0 to 360)
- saturation- the saturation value for the HSB color (from 0 to 1)
- brightness- the brightness value for the HSB color (from 0 to 1)
- Throws:
- IllegalArgumentException-- ERROR_INVALID_ARGUMENT - if the hue is not between 0 and 360 or the saturation or brightness is not between 0 and 1
