My object is completely black after sculpting

I’m a beginner to using Blender for 3D design/graphics and I’ve been encountering issues while sculpting my object here. Once I take it out of sculpt mode, it does not turn light gray and remains black instead. What should I do to make my object gray?

Try changing Viewport Shading settings
