I took Lomography Purple with me to the south of France, and was excited but very nervous to shoot it. I shot it over two sunny (if anything too sunny!) days, at ISO 200.
I had read "Greens become purple, yellows become pink, blues become turquoise, reds remain red" and that was largely true for my experience - although it was so sunny that a lot of my greens moved more towards pink. But I have no complaints about that, my main concern when shooting had been that I would have more purples than pink!
I'll definitely be purchasing more of this film, I'm already dying to use it on my next trip to Scotland, and I can't wait to see how it performs differently on a more moody overcast day. I do think the amount of light (and, of course, your ISO choice) has a big influence on what style of tones your images will lean towards.
For me, personally, I wouldn't use it to shoot anything other than nature and landscapes.
I only wish I could load more sample shots, because there were very very few duds!
