I can't texture paint on the 3d character

I can do it now. I think it had something to do with selecting the right texture in the texture menu.

I am doing a beginner tutorial here: https://www.youtube.com/watch?v=yHTakjMTVWQ Following the tutorial, I made a second slot for “color details” on the face. For some reason I can’t paint directly on the 3D character, only on the UV Image. I am going through this tutorial for the second time. I was able to paint on the 3d model the first time I did this, but I can’t do it now. Can someone tell me what I am doing wrong?
