The deep green on the left just speaks to me!
I was digging the left one too, it really “pops” with more yellow. I almost bought one of these yo-yos during the 20% off YYF sale. Someone beat me to the last one. Ugh, it was just not meant to be. But, I see them in stock elsewhere, so there’s still hope. 
Right.
It’s like a color-shifted freeze-frame of petals being blown off of a flowering tree.
I own that same color Primo.
Left I like the extra gold
I like more green on the right. The left makes me think of throw-up.
It looks to me like the camera auto-selected different “scenes” (exposure and colour settings) for each. The deeper green and more gold is partially an illusion.
