Limit blend mode to certain layers?

[#1]

Hi folks,

Please take a look at the video linked below.

In it you can see i have a blue stripe over a yellow stripe.

When i change the blend mode to "difference", the area of intersection turns purple, but the rest of the blue stripe also turns red.

But if i turn off the white background, i have blue again. So i guess when you give a layer a blend mode, it effects how that layer interacts with everything below it in the layer stack.

But perhaps i ONLY want that blend mode to be effective on the layer right below it?

Is there an easy way to achieve that?

Thanks!
