I have drawn two boxes of red and green (solid). Since they are of
smaller size than the background, I am able to move them around using
the cursor.

When I overlap one over another, the one on the top hides the bottom
one.

How can I add these two colors? I.e. in the area where red and green
are overlapping, it should become yellow.

I want to do it with out reducing the opacity.

Does anyone know how to do it?

Thanks in advance.

I don’t know why you would want to do this. But since the colors
are solid it is easy.

1) Place each color on a separate layer. (layer 1 and layer 2
with layer 2 on top)

2) Change the layer 2 mode to “difference” ……. Still not the
color you are looking for.

3) Click Select then Color Range. Click on the overlay color with
the eyedropper to select it. Then click okay

4) Press “Ctrl I” to invert the selection. ……… Viola.

Here's a variation on Still Waters' method that gives you a
little more flexibility.

1) Create the areas of color that you want on separate new
layers.

2) Change the layer mode for all but the background layer
to Difference.

3. Fill the background layer with 50% gray.

4. Turn off the visibility of the background layer. Voila!

With this method, your overlap area is not fixed. You can
move the color blocks as much as you want, and get the
effect of adding the colors with cutting a new mask.

If you are using the color overlap area(s) as a filter over
another image layer, one way to accomplish that is put the
layers created above into a group, change the blend mode to
Overlay, and reduce the visibility to get the desired effect.
