Java AWT - Color Class

You can utilize the inherent Java hues which are characterized in java.awt.Color. Here are a couple of models. 

When building a Color with an express alpha or getting the shading/alpha parts of a Color, the shading segments are never premultiplied by the alpha segment. 

The Color class is utilized to embody hues in the default sRGB shading space or hues in subjective shading spaces distinguished by a ColorSpace. 

Look into the rest in the Java library documentation. 

import java.awt.Color 

Pen = new Pen(); 

pen.setColor( Color.RED ); 

pen.setColor( Color.GREEN ); 

pen.setColor( Color.BLUE); 

pen.setColor( Color.BLACK ); 

Choice of valuable RGB hues. 

Make another shading by jumping its red, green, blue segments: 

import java.awt.Color; 

open static last Color VERY_LIGHT_RED = new Color(255,102,102); 

The Color class makes shading by utilizing the given RGBA values where RGBA represents RED, GREEN, BLUE, ALPHA or utilizing HSB esteem where HSB represents HUE, SATURATION, BRIcomponents.
