Indigo, Jet Black, Platinum Silver, or something a little different. Start with the color that feels like yours.
The current collection gives each GameCube controller colorway its own page. Compare the name, model, price, and collector details, then save the ones you want to revisit.
Color is only part of the choice. Check the condition notes and ask for photographs of the exact controller before deciding. A color reference helps you browse; it does not document wear or included items.
