1. **Blue** - Start with the vibrant and lively blue as your first color.
2. **Grey** - Next, add grey for a softer transition that balances the blue.
3. **Black** - Introduce black; it will add depth and contrast nicely with the other colors.
4. **White (Rim)** - Finally, finish with a white rim. This will provide a crisp and clean outline, really making the colors pop.

This combination will be striking and has a nice progression from the darker colors to the bright rim. Enjoy your crocheting!
