Collage Generator.

Over the last couple of weeks i have been using 6 DL.3's on a Full Boar Console and a Jands Vista.

So i am having some issues with the Collage Generator. The Issue im having is that when i blend the Dl's together i keep getting a yellowish blending overlap. I have tried many different Effect modifier's that have been suggested on this website but none of them are working.

I was wondering if i could increase or decrease the amount of blend to maybe brighten the overlaping edges so it does not look so yellowish or dark...

Thx
