He’s adorable! I think he is a seal lynx point because around his nose and the backs of his feet are already quite dark, and, as a colorpoint, he will probably continue to darken up as he grows and matures.
Not a lilac, as that would be much lighter in color, especially at this age... pointed kittens start out very light in color and darken up as they mature. Could be chocolate or seal lynx point. In general it looks more like a seal lynx point. An adult seal would be expected to have darker paw pads, but this is still a baby and the color is still developing. If it's a random bred domestic cat and not pedigreed, it's almost certainly a seal, as chocolate is rare in the general population.
