i agree w/ Dr. Ash. an all white BlackEL like a patternless Super Fire will be brighter and whiter than white BlueEL's. also i have an adult Lied (Lesser Pied) who has stayed all white since i got her as a hatchling. the whites in Pieds stay white and vibrant but sometimes they do develop a black freckle here and there butt i haven't seen that on all white Pieds yet.
