It's certainly an intriguing colour - like others have mentioned before, it can change hues depending on the lighting (and cleanliness, I suppose). It can be a very classy tone.
To my eyes though, it's the kind of colour that an older person might buy. I think it says "retiree who would drive a Buick if GM weren't circling the drain". I certainly don't wish to sound age-ist, because God knows we all end up there, and usually a lot sooner than we expect. But colours like black, dark grey and red held a great deal more appeal for me than the Pyrite Mica when I was making my purchasing decision. I think they better accentuate the "sport" part of the SUV aesthetic on the RAV4.
That being said, beauty is in the eye of the beholder. What do I know? If you like it, I couldn't be happier for you, because you got a great vehicle and a look you like.
