The gene that causes the pointed coloring in himis and siamese cats is actually temperature sensitive.  When color pointed kittens are born, they are solid white, as their body is exposed to colder temperatures, their fur gradually starts to darken.  With time and exposure to cold temperatures color point cats can almost turn solid colored.

For example, I have a seal point siamese.  He's getting a little older and his whole face, arms/legs, and tail are black.  He's also starting to blacken up on his shoulders...

I was just using white as a generic term, next time I'll just say 'soild pale color' lol.  You are correct though, I can tell what color most of my kittens will be the day they are born.  I love lining up my kittens when they are first born to see the difference in shades.

I don't have any pairs that will produce flame/cream points yet, so that's a battle I haven't had to face yet.  I know that I have a tough time with chocolates and blues and first.  They are born about the same shade and until their fur grows in look a lot a like...  My first litter of CP's was 4 kittens, 1 seal, 1 blue, 1 chocolate, and 1 lilac.  It was a great learning experience

I can see by reading in this site it takes a lot of practice to be able to distinguish the points or some colors. I was told once, that my female that was registered as a chocolate tortie point is actually a smoke point. Would i have to go back through CFA to get that corrected? Also, should I have them DNA tested for the coloring? I am not all that familiar with this like some of you are. I actually have had a small amount of time I have been reading on the forum and looking at reference points people have mentioned and am learning from it all. I was told that kittens eyes open in 10-14 days plus or minus. How many days should you wait before you get worried. My problem is my male mated with the female a whole week before I contained them so the kitty even though he is big, might actually be younger than the other one whos eyes are open. We have English Bulldog babies that the vet inseminated  about 4-5 days from the initial insemination date, the other breeders said it should have been the next day and we were lucky that the younger ones didn't die. So with them the eyes opening were different as well as their size compared to the bigger ones. Is this true of cats?
