I have made a model of a building. I was using the make face tool, but when I extruded it, it was a different color than the rest. enter image description here

Its not any different material or anything either... enter image description here


You need to reset your normals, go into edit mode, select everything A, and hit Ctrl-N.

This happens when blender incorrectly guesses which way the face normal should be pointing when you make a face, it happens from time to time.

  • $\begingroup$ @user3658408 Quite often it happens when you extrude a face in a different direction, scale by a negative amount, or fill mesh faces in an unexpected order. $\endgroup$ – VRM Mar 5 '15 at 1:39
