Good luck with that!
FYI Lemon Blue doesn't breed true and apparently I was told brown reds don't either (I thought they did)
I also love the color and have been looking for eggs, chicks for a very long time, and no matter where I turn or who I ask they all say no or they don't know....geez I've ask help with color genetics not much help there... and if I ask a breeder they ignore me. The colors have been around a long time but they sure are hard to get a hold of for being older colors. I guess its some kind of secret???? If you can't tell I'm very frustrated!!!!! I've had shipped eggs sent (several doz) from the east over the past couple of years but since I'm in Idaho and they are so far away, nothing hatches.
Like you I'm just a backyard chicken lover that doesn't show.
