I'm working on Blender VFX and I'm using a blur node. This weakens the colors and I am trying to use a Math:Multiply node to strengthen the colors. However, when I use this node, it turns the transparent background to black. Is there a node that strengthens colors but does not change the background, or a node that changes transparency based on how dark the image is.
EDIT:: Unfortunately, palkomino's answer doesn't really help. The RGB Curves node does nothing!
I need a result like the Math:Multiply node, but with a transparent background.
