The larger the litter, the smaller the kits (assuming the same breed, of course!) This frequently continues to be the case as they grow, too. Apparently, does only produce a certain amount of milk, and the more mouths it feeds, the slower each one grows.
But as to the color of the kits - a pedigree only takes into account the rabbits that are direct ancestors; if you knew what their siblings looked like, you might have a better idea about what might be wandering around unseen in your gene pool. Lilac is a combination of several recessive genes, but there are still a few dominants at play in a few loci. Castor is the result of the expression of dominant traits across the board, so you have the potential for carrying a whole bunch of unseen recessives. REW from that combination wouldn't surprise me at all. Rex also do Cali/Himi/Pointed White; you probably ought to watch the white kits to see if they start to develop dark points (usually shows up first on the tail, then the tips of the ears and toes).
