^ nope, the Nature and the Angel lens are the same brand. Both are manufactured by NEO.
Nature is three-toned (more similar to Freshlook Colorblends) and Angel is two-toned(more similar to Bescon Tutti).
InfiniteTime, here's a link to the Dueba site so you can see the difference in lens:
http://www.duebacon.com/eng/There is really little difference in the overall appearance once you've put on the lens-- but if I had to be extra picky, I would say the DA-1 are better for already dark eyes and DS-22 are good for medium brown eyes that want the big, completely black effect.
Bunny and mmitsjojo both posted pics of their Free Teen Violets, but you'll have to search a little ways back to find them. Both said they were very dark--the color wasn't noticeable (on very dark brown eyes).
bliss82, some pages back, AmikaSaysHi posted pics of her Floral Greys. Check again: they are in the same posts that she modeled her Nudy Green and Nudy Blues.
k!tty, don't worry! I definitely had a hard time putting in contact lens the first time. I think it took me 45 mins to get one in and an hour to get them out

;; Just take it easy and relax when you put it in your eye. I recommend looking on google for a tutorial with pictures (there was one in this thread, but I don't remember the page).
_FallenAngle_, I also don't wear contacts (other than cosmetic) and at first, my eyes got dry and tired. It takes some time before your body is used to sticking things in your eye >.<
