You have to import the textures you used in Google Sketchup as well! When you save a sketchup file it comes with a folder that has all the textures you used in it! You have to import those and put them on your model! If you didnt use textures you can simply change the color of the material in the Unity Editor. Just look at the cubes material in the inspector and change the color to what you want!

When you are exporting goto options on the export menu and look in there. Also when you export from sketch up all your textures are placed in a folder. You may have to import these too blender too.
