I have a male orange ghost, I kinda really like him. Not sure about the others. According to WOBP.com "Ghost - Also known as Hypo or Hypomelanistic. The “Ghost” is a recessive mutation that reduces the black pigmentation. Although there are many different lines of ghosts, they generally follow the same general description. Ghosts are varying shades of yellow, brown, grey and green. Their sheds are always clear much like albinos, with faded dark colors with a faded head. A ghost will always appear to be in shed or always seem to have a hazy appearance."

Here's my 2010 male OG.
