Properly labeled pink snows will gain more pink as they age. All snows hatch out with varying levels of pink, but regular snows might get a little pink, a little yellow, and lots of white. Coral snows, salmon snows, red factor snows will gain plenty of pink coloration. Unfortunately, some less informed breeders (and some unscrupulous ones) will label regular snows as something they are not, so look for ones that already have fairly saturated pink. And like Tonya said, seeing pictures of the parents can be helpful as well.
Carol has some really lovely pink snows. If you look at her pictures here:
http://www.cornsnakes.com/forums/sho...d.php?t=147360 you can see how they have little spots of extra pink in the little dots down their back - that's a pretty good indication that they will be very pretty pink adults. If you look at this picture of a regular snow I hatched several years ago t's slightly pinkish like all snow babies, but ended up being a normal looking snow because it had no extra red enhancing genes.
