Pain lands is the term that typically refer to the land cycles first printed in Ice Age and Apocalypse. However the term can be applied to every land, which deals "pain" damage to you every time you tap it for colored mana.
Original pain lands
The lands providing allied colors were printed originally in Ice Age, those providing enemy colors in Apocalypse. These lands were first referred to as pain lands, even though City of Brass was printed earlier. The former were reprinted in Fifth Edition, Sixth Edition, and Seventh Edition, the latter in Magic 2015 and Magic Origins. The complete cycle of ten lands were reprinted in Ninth Edition and Tenth Edition.
In addition there exists the Grand Coliseum, which can tap for mana of any color.
