Each level within the Portal series consists of surfaces. Typically, any white flat surface can house a portal for the player to use, whereas an uneven black surface cannot be used in this way. These are used as the basic structure of any given puzzle.

As recently introduced in Portal 2, conversion gel will paint any surface white to allow for portal use.
