I bought a colour change andesine from the old Gemstv a few years back( it was with the usual hype about rare rare rare and I got sucked in like you do ) the stone in daylight is a very dark green with flashes of almost neon green which I like, but to see any change of colour I have to shine a torch on it then it goes a reddish colour ,though as I dont keep a torch handy when I wear it I just pop it on when I want to wear a green stoned ring I do like the design and the cushion cut so I'm not unhappy with it I dont think its what its all hyped up to be thats all.
