When they at young age, they came out white and eventually it get some yellowish not like tremper albino at young age they already yellow. And guess what, by calculating the gecko genetic
They won't all be snows. The yellow ones aren't and the white ones are. I do agree though that it can be hard to tell. I had 2 females (mother and daughter) who produced offspring that were are really pastel yellow and it was impossible to tell whether or not they were snows or not. There is a thread on here somewhere about "pastel Mack snows" that indicates that there may be some variants of the Mack snow trait that look a bit different. See if you can find that thread.
If the hatchling is brown and white than it is a snow tremper, if it is black and white than it is a snow het tremper. You said you hatched out a dark one, so that is a possibility.
I don't see any pictures of a pink and white gecko?
It's probably a light snow tremper. Just like how some albinos can be dark brown and yellow, some are pink and yellow. If it is a snow, substitute white for yellow.
The lighting makes it hard to tell the exact coloring of the geckos. They are both definitely snow. Again, 50% snow trempers and 50% snow het trempers. So if one is not albino, than it is a snow het tremper.
