Extending the Color class

Newbie & Debugging Questions
#1

Hi, I’m trying to create additional methods for the class java.awt.Color:

public class Color extends java.awt.Color {

	private static final long serialVersionUID = 1L;

	public Color(float r, float g, float b) {
		super(r, g, b);
	}

	public static Color blend(Color c1, Color c2, float f) {
		return new Color(0F,0F,0F,0F);
	}

}

However, when the method blend is called Eclipse says “The method blend(Color, Color, float) is undefined for the type Color”.
Do you have any suggestions what may be the problem?
