Thanks! I hope they're doing well for you!
It really is hard to photograph just how pink the pinks are. They are really pearly pink from itty bitty things. The blues are nice, but not really a noticeable blue until they're at least pea-size, and they get more distinctly blue as they grow. It takes plant lights to really make them stand out, light or natural river-rock colored gravel makes you take notice of the blue as well. Adult blues are a pretty blue snail, but the pinks just don't look real - they look like a child's fantasy snail.
