RELs may end up being quite white as well, but I have a feeling that RELs from BluEL group may still end up with a hint of colour bleeding through.
Just to make sure we are talking about the same thing with the eye line - I am reading this to mean how the lighter gold eye-stripe is basically outlined in darker brown right along the top. Is that correct? If so, then I can report that the hatchling PhantomPin, hatchling PhantomPin combo, and my breeder female PhantomPin all have the dark line.
I would post pics but ever since Photobucket went stupid it has been too much of a hassle for me to find a now place to host pics so I can put them up. I can email you pics if you would like (hit me up via PM with your addy).
