Q: How do you gain stars and colors for my trainer card in Pokemon Platinum for the Nintendo DS?
A: Unlocking colors for your trainer card in Pokemon Platinum requires you to gain stars, which are only unlocked when completing certain events:
- Win any Master Rank Super Contest
- Win 100 consecutive battles in the Battle Tower
- Defeat the Elite Four
- Earn a Platinum Flag in the Underground by getting 50 flag captures
- Collect all 493 catchable pokemon (this does not include special event pokemon)
Each of these will grant a single star, and unlock another color for your trainer card:
- One Star = Blue Card
- Two Stars = Bronze Card
- Three Stars = Silver Card
- Four Stars = Gold Card
- Five Stars = Black Card
