How to continue learning more about Spiral Dynamics?

[playdoh]

So I'm really interested in Spiral Dynamics. I've already watched Leo's videos on YouTube about SD and now want to know how can I learn more about to become even more green and yellow. What should be my next course of action be? Are there any good books you can recommend, courses, etc...?

Thanks.

P.S. is there anyway to find out what color I am? I started taking that quiz on sdtest.ru but didn't seem it would give such accurate answers, as you need to be completely unbiased with yourself.
