Reading the APA standard, the description of body color refers to page 37 - the blue Columbian.
The SOP for blue does not refer to 'Columbian'...it is referring you to page 37 which is the description of blue under the heading of the blue variety of Plymouth Rock...I believe the intent was to avoid repeating the description for every breed with a blue variety...they refer you to Silver Dutch Bantams for the Silver Ameraucana color...
What about Blue wheatens?
I think you need the same pattern genes to get any true lacing..if you want blue lacing, maybe you need to adjust the effect of the melanizing genes?? the thing about the edging is that it is a diluted black, it is a lack of color.. opposite effect of lacing. with out Pg, and Ml, you don't push the black to the edge..I'm guessing that it would be very difficult if not impossible to get that effect in blue wheatens..
I would still debate whether it was necessary to bring in black to avoid the over-dilution of the blue from time to time
Two thoughts...all blue are not the same...some are darker than others...and you can use black if you have a good idea of the genotype...
Granted, if the lacing is from the combination of pattern genes, bringing black back in won't help lacing, but it definitely would add some of those melanizers back in to darken the blue again.
Still an 'if' there????? we are not talking about making dark blue...SOP dosen't call for that, just calls for an even shade of slate...depth of blue is personal preference as far as I can tell..
