[Solved] Texture paint + textures

[sweet pawn]

How to make my texture paint have a transparent background? I want to add a puddle with texture painting, but when I try to mix it with my textures it becomes desaturated and the color fades

in what way are you mixing it with your textures? pls show node setup

You need to create a new image to paint on and use the alpha. Go to the black default Color when selected and make sure the alpha is 0. you can than paint on the transparent image and use the alpha as mix factor for a mix rgb.
Alternatively bake your textures and paint over them
