Class Blend

java.lang.Object
javafx.scene.effect.Effect
javafx.scene.effect.Blend
public class Blend extends Effect
An effect that blends the two inputs together using one of the pre-defined BlendModes.

Example: 

Blend blend = new Blend();
blend.setMode(BlendMode.COLOR_BURN);

ColorInput colorInput = new ColorInput();
colorInput.setPaint(Color.STEELBLUE);
colorInput.setX(10);
colorInput.setY(10);
colorInput.setWidth(100);
colorInput.setHeight(180);

blend.setTopInput(colorInput);

Rectangle rect = new Rectangle();
rect.setWidth(220);
rect.setHeight(100);
Stop[] stops = new Stop[]{new Stop(0, Color.LIGHTSTEELBLUE), new Stop(1, Color.PALEGREEN)};
LinearGradient lg = new LinearGradient(0, 0, 0.25, 0.25, true, CycleMethod.REFLECT, stops);
rect.setFill(lg);

Text text = new Text();
text.setX(15);
text.setY(65);
text.setFill(Color.PALEVIOLETRED);
text.setText("COLOR_BURN");
text.setFont(Font.font(null, FontWeight.BOLD, 30));

Group g = new Group();
g.setEffect(blend);
g.getChildren().addAll(rect, text);

The code above produces the following:
