I am a beginner in pendulum. What kind of pendulum should I buy?

A white pendulum or a purple pendulum is recommended.

You think you can use other colors after you know this pendulum. Of course, don't stop the previous pendulum just because you know your first pendulum and have a second pendulum. They will be sad, too. If you communicate with them with your heart, you will feel their presence.

These are for your reference.

Haihe: Forget your tears, calm down, balance your emotions and protect yourself.
