Considering monty was very careful with choosing team rwby's names and the bees are constantly visually shown to represent the yin and yang symbol in their fights, I think its safe to say yang is meant to embody well the principle of yang and blake embodies the principle of yin
You could write an essay on the similarities between bumbleby and the philosophy of yin and yang, (sun and moon, dragon and tiger, light and dark, fire and shadows, heaven and earth (yangs weapons are called heavenly fire and the faunus originated from the shallow sea according to rwby fairytales)) etcetera
Yin and yang are complimentary you can't have one without the other which other characters have remarked upon multiple times in the show
Someone smarter than me could probably expand on this and put together my jumbled thoughts together better
