sculpting with different colored mesh panel

Hello everyone, a quick question. Most times, when I watch a sculpting tutorial, they change the mesh color through a panel not sure how I can get to.they open it up usually on the right like you’re pressing N and just choose the the color they want for their mesh without bothering with materials or anything. I looked under that panel under display, but I couldn’t find it.how can I find it? Is it through preferences settings add on or something? Thanks in advance

N Panel->Shading->Matcap
Enable to select one of the matcap textures. You can’t select an user-defined one, though.
