Whenever Roxanne, Starfall Savant enters the battlefield or attacks, create a tapped colorless artifact token named Meteorite with "When Meteorite enters the battlefield, it deals 2 damage to any target" and "{T}: Add one mana of any color."
Whenever you tap an artifact token for mana, add one mana of any type that artifact token produced.

Roxanne doesn't care about any restrictions or riders the artifact token put on the mana it produced. The additional mana Roxanne produces won't have any restrictions or riders.

The additional mana is produced by Roxanne, not by the artifact token that you tapped for mana.

The types of mana are white, blue, black, red, green, and colorless.

You're tapping an artifact token for mana only if you're activating a mana ability of that token that includes the tap symbol ({T}) in its cost. A mana ability produces mana as part of its effect.
