EffectsTest-Blend-Swing.png -- blend effects with Swing toolking
EffectsTest-Blend-Prism.png -- blend effects with Prism toolking
EffectsTest-Blend-diff.png -- color difference between first two (black color means no difference).

Note, for COLOR_BURN effect difference is huge.

Code providing each images is next:

new Group() {{
                        setBlendMode(blendMode);
                        getContent().add(new Rectangle(20, 20, 60, 60) {{ setFill(Color.rgb(0, 50, 255));}} );
                        getContent().add(new Circle(70, 70, 30) {{ setFill(Color.rgb(255, 150, 0, 0.7f));}} );
                    }}
