Trying to make nightvision with multy UI_mask

Hi, so im trying to make a night vision effect with the multi UI mask.
I want my regular effects to be in the pink, som mirror/reflects in the blue and the green nightvision in the yellow.
But its acting up, effects are applied in the strangest way... Am i doing something wrong? Is there a better way to split the effects on the screen?
With UI layers, can you have the same effect in different layers with different values for example?
