Shaded mode of model objects are different

[Anonymous]

I've made an object using Create Polygon Tool but why is my object is in a different color than the regular object. With regular object I mean that when I use e.g Polygon Sphere tool that object is grey but the object I've created with Create Polygon Tool is black.

Below is a screenshot of what I mean. Left is the object that I've created with Create Polygon Tool and on the right is with the Polygon Sphere Tool.

You are looking at the back side of the mesh, that's why is black, the normals are facing to the other side, a sphere is a 3D object so the normals are facing out in all directions, the Mesh tool creates a flat plane that has no thickness, you can extrude and it will turn grey...you can also reverse the direction of the Normals if you want or just rotate the mesh  to face the camera.
