Using the Screen mode
How to do it…
This simple recipe will show you how to change a layer mode to the Screen mode:
In the Layer palette, click on the layer to edit (if the Layer palette is not visible, go to Window | Layer to open it).
In the top-left corner of the Layer palette, click on the drop-down menu. Then, click on the Screen mode.

Again, the black outline of the rectangle has vanished, leaving just the white fill as a void in the yellow and purple stripes. The areas where the blue and red vertical stripes crossed the white now have no color to them. Where the blue and yellow stripes cross is almost white; it's so pale! The region where the blue and purple colors meet has become light blue. The red stripe has had almost no effect on the yellow one, while the red and purple overlap has turned into a lighter violet color.
What the program is doing is inverting the colors below, and then multiplying them with the layer being configured. The colors become brighter after this...
