Wow, that is a sweet one, and highly unusual. Seems to be a point, but no blue eyes. Seems to be a dark point, probably seal, but is probably diluted tortie. Longhair to thrown in. Most pointed cat breeds are shorthairs... so difficult to find a comparison.
OK, the main riddle: point, but not blue nor even bluish eyes. so probably a combo of the point of the siamese and burmese type. Not common - but not totally unique once we learn us to see and recognize them.
Another indicium is you dont tell my cats, you say my kittens. Siamese type Points, especielly seal points, do darken up with time, but they arent darkish already as young kittens. But this happens with them half burmese points.
So the diagnosis is clear: point of the combined burmese and siamese type.
Probably diluted tortie.
Breed is domestic long hair, DLH. We could perhaps compare her to a Somali, but somalis arent known to be points, although some of them ARE bluish. so a atypical Somali, if its important for you to put a fancy label on her.
The other one is a more regular lynx point of siamese type, probably blue in color of the point. Lynx means tabby when talking about points. The kitten seems to be medium hair. So perhaps compare to Balinese??
I think StefanZ covered everything, I'd just like to add that the white hairs on the darker kitten (you can see it too on the other kitten, just less visible) is a possible fever coat, the result of the mother having an infection while pregnant.

Very unique babies! I agree with the above statements but your darker kitten is stumping me. He looks like a fever coat, but then again he does not due to the blaze between his eyes. Keep us updated with pictures as they grow so we can see how the colors develop:-)
