# Swiss German Jass Card Suits and Their Colors
Based on research from Wikipedia and the Wikimedia Commons, the four suits used in Swiss German Jass cards have the following characteristics:
## Suit Names and Colors
1. **Schellen** (Bells)
- Color: Typically gold/yellow
- Description: Features bell-shaped symbols
2. **Rosen** (Roses)
- Color: Typically red
- Description: Features rose flower symbols
3. **Schilte** (Shields)
- Color: Typically green
- Description: Features shield symbols (often with fleur-de-lis designs)
4. **Eicheln** (Acorns/Whitlow Grains)
- Color: Typically brown (like acorns)
- Description: Features acorn or nut symbols
## Additional Context
These are the traditional Swiss-German suits used in Jass card games, particularly popular in Switzerland and the Alemannic German-speaking regions of Europe. They are distinct from the standard French suits (hearts, diamonds, clubs, spades) and are part of the Swiss-suited card system.
The suits are used in various Jass variants including Schieber, which is the most common variant played in Switzerland. The card deck typically consists of 36 cards with these four suits, each containing cards ranked A, K, O (Under), U (Ober), B (10), 9, 8, 7, 6.
