Hey, I'm new at photoshop and I'm trying to make a basic sig with an abstract brush. I brushed the first part and used color balance on it, then made a new layer above and brushed it as well. But i want the newer layer to have its own color balance, but if i create a new colorbalance, it effects everything underneath it. How do I make it so it only effects the layer underneath, and not the previous one i already have color balanced
