There are a lot of sunglass/goggle sites that give you all the colors and what light they are best for if you "Google" them. I went with a goggle I loved with lots of replacement lens options for different light conditions, so I only had to carry one pair (I have a back up pair, but don't like them as well) and can change out the lenses depending on conditions.
I used to not be a big fan of goggles, wearing them only when I really had to, but I am loving them now. I have a cool pair of Spy Goggles, below (yeah, I'm flamboyant, why not!?) which I got off of SAC, but they have them at Backcountry.com for a few more $$$. Besides this funky pair, they have tamer ones...
I have bronze/silver polarized for sunny conditions and just ordered locally for $19 (big on line retailer, apairofshades.com, that happens to be local, near my ski clinic location, so I can pick them up, no shipping costs) a pair of
persimmon colored lenses, as they are supposed to be best for flat/low light, although like it's been said here already, I don't know if anything is spectacular in flat light... I also will pick up a pair of clear for night skiing too.
These goggles, although last year's model, works great for small faces (women, jrs), are comfy, and fit over my glasses (extreme dry eyes, Sjogren's Syndrome, means no contacts, except on special occasions, and no laser surgery for me), even though they are not billed as being able to accommodate them. They also are supposed to be helmet friendly. I love the comfort and performance of these goggles and they have made me a goggle convert!
