Purple can refer to the old purple team, which originally spawned on the upper right side of Summoner’s Rift before visual updates standardized the map’s team colors. Although this layout no longer exists, long-time players may still use the term informally when talking about past versions of the game or older lane setups.
Purple is also used to describe the Hand of Baron buff, commonly called Baron Buff or Purple Buff because of the glowing purple effects it grants to champions. This powerful Buff enhances minions, strengthens pushes, and helps secure key objectives, making it one of the most impactful advantages a team can obtain in the mid to late stages of a match.
