Using the Lighten mode
How to do it…
This simple recipe will show you how to change a layer mode to the Lighten mode:
In the Layer palette, click on the layer to edit (if the Layer palette is not visible, navigate to Window | Layer to open it).
In the top-left corner of the Layer palette, click on the drop-down menu. Next, click on the Lighten mode.
How it works...
This mode works on the colors in the top layer and the bottom layer, and combines the color in the bottom layer with a brighter color. In our preceding example, the blue and red stripes have all but disappeared. In fact, only a lighter yellow rectangle remains where the blue and yellow lines overlap in the upper-left corner. The black outline of the central rectangle has disappeared and only the white fill remains, leaving a void in the center of the image. Because the Paper color is white, wherever the vertical stripes overlap the Paper color, they turn white as well, causing them to disappear.
