I'm a beginner in Blender, so forgive me if this description is simplistic or the solution is obvious.

I am trying to paint on a black image texture on the solid. The texture looks like this. enter image description here

But when I make even a small stroke on the top, the whole thing turns gray with a couple of black spots at the bottom.

Before: enter image description here

After: enter image description here

I've asked more experienced people, and they don't know what's going on, and I can't find anything online. What's going on here?

And I guess here's some more screenshots to see if those help.

enter image description here

This is the UV map. enter image description here

I don't understand the reason for the Polish mask to be truthful to you. You probably have overlapping geometry with different materials. But I can't see your objects to help you. What I would do is remove the Polish Mask image and rewire the principled bsdf to your material output since you have everything there. Then since I understand you want to paint the Base Color image I would pick the base color image and paint on it. I wouldn't change anything else besides looking for duplicate objects of the anvil.

Something is clearly wrong with the material because you can see this grey anvil has a normal map. Since you haven't connected the normal map image to your output it's impossible the material you are showing to be the one we look on the top image. Because the Polish image you have connected is a simple image with no detail, no normal or anything. The anvil should look simple low poly.

My guess is this. 2 same anvils overlapping. One has the material with the polish mask you show us and one has the principled BSDF with all the images connected to the Principled BSDF like the third image and then to the output.

Next time include the whole screen please. Let's not play find the problem with as less clues there can be.
