Materials add color and texture to a model. They work like paint, carpet, siding, and basically any other kind of texture. Materials can only be applied to a face so if you want to apply a glass material to a window, there needs to be a face for the window, rather than an empty space.
All the materials available directly in SketchUp are categorized in the drop-down menu in the Materials/Colors panels.
You may need to add lines to the tops of your walls so that you can make the two walls different colors. Just use the line tool to draw straight lines across the inside edges of the wall.
The 3D Warehouse is a place where you can find objects, materials, and other entities that you can add to your model. This is a great place to find furniture and decorative objects, as well as more unique materials and textures for your walls, floors, and windows. You can even find actual objects and materials from real catalogs.

You may have noticed that we didn’t add a floor material to our model. That’s because we’re going to find a floor in the 3D Warehouse! Rather than trying to match our actual room 307, take a look through the 3D Warehouse and find a flooring material you want to use. You can choose anything you want.
Return to the 3D Warehouse to find and place the following objects:
Note that you may have to rotate your objects to place them on the walls where you want them.
