I have a really cool effect that I like what I did using the sks files in xcode and in blend mode "add". Now I did not understand this at that time, but, looking at the documents of the apple, I saw that the effect is actually based on the background color, in particular:
Adds pixel values ββof the particle and main images. Creates a white pixel if this value is greater than 1
Now I want to have the same effect for each background color, but as far as I know, the only way to do this is to use the Alpha blend effect. But it only gives me the opportunity to have solid colors. This is the graphic that I want to apply in all different background colors:

How can I use this effect for all background colors? I use the default particle search file.
UPDATE:
I leave this question unanswered until a single apple finds a way to do what I want, or someone else finds a way to do it.
