What it does
"Vivid" isn't an official Magic keyword—you're likely thinking of the Vivid lands cycle (Vivid Crag, Vivid Creek, Vivid Grove, Vivid Marsh, Vivid Meadow), from Lorwyn. Each enters tapped and produces its own color of mana for free, but also enters with two charge counters. You can remove a charge counter to add one mana of any color instead.
The key nuance: once those two counters are gone, the land only taps for its single native color. People often treat them like unconditional five-color rainbow lands—they're not. You get exactly two "wildcard" activations per land before it becomes a basic-quality tapland.
In Commander, they're solid budget fixing for three-plus color decks, especially helping cast off-color spells or splashes early. They synergize nicely with proliferate or ways to add counters, effectively refueling your color flexibility for repeated free fixing.
