Create the objects that you want to blend together. Click on the object that you want to blend with and press “Ctrl-Shift-]” to place it on the topmost layer of your artboard. Click on the “Transparency” tab with the object still selected to bring up blend mode options for that object. Select “Lighten” from the drop-down menu, and then use the “Opacity” menu to select an opacity value for the object. The higher the opacity of the blend object, the lighter the final blended area will be. The object changes automatically. Click and drag the blend object to move it over the top of the base object. The Lighten effect takes place where the two objects overlap. Writer Bio
