The best way I can describe it is that it's about halfway between anery and ghost when they hatch, and it's most noticeable, especially as they age, that they don't brown out like anerys and ghosts. They seem to be the "cool color" version whereas anerys and ghosts always look "warmtoned".
They shed clear, with no hint of melanin in the shed skin, which leads me to believe it's a mutation that causes a lack of or dysfunction of the dendrites (fingers that reach up into the outer layers of skin) of the melanosomes (black pigment producing cells). Normally the cell shoots projections up into the epidermis (outermost layer of skin) and these fingers with pigment in them break off and are shed with each shed skin. Even though they are quite darker than ghosts, they don't shed the pigment in the skin.
Could be that these dilute animals look the way they do due to all melanin being under the iridophore (reflective cell) layer, so the warm tone browns aren't showing (like they do when they are at the surface), but rather look more bluish/blackish, just like lavenders look silvery/purple.
