Lilac and tans are just stunning and very rare as they need double copies of 3 sets of rare recessive genes. They must have a double copy of the blue gene, a double copy of the chocolate gene, and a double copy of the tan points gene (or a copy of the tan points gene and a copy of the recessive black gene). They have a little lighter, more lavender toned coat than the blue & tans and they have light eyes as adults similar to those of chocolates (hazel, yellow, or gold).
