See this image:
I really don't know how to describe this but I'm getting a weird overlayed color from the magenta waves when I put them over my background.
As you can see I have the blue rectangle and then I want to put the magenta wavy lines on top of it but instead I get this weird overlay effect as if the waves were below them.
I tried making a separate layer and put the background at the bottom, I've tried to send the rectangle to the back, send it backward, etc.
What is wrong with it? Thanks so much.
