Question about the Adidas xeno colorways

[johndoe]

The Adidas xenos really confused me at first, I first thought it was 2 different colorways, then thought they could be "turned on and off", to finally realize they simply change color with the light.

However, now that I may want to buy some, I'm even more confused as I learned they come in 2 colorways (I think I'd get the superstar model). It seems they come in both black or grey when they are "off", but since many sellers show them "turned on" where they are multi color, how am I supposed to know what colorway I'm buying?

I want the ones that are black when they are "off", what's the name of both colorways as that's probably the best way to know what color I'm buying.

Thanks
