Danne Honour is widely considered the Dean of Buff poultry. He complied this great collection of hundreds of articles on breeding Buff Poultry.

http://www.aviculture-europe.nl/Buff-Coloration.pdf I was online one day someplace on the Net and inquiring about the proper color of Buff Poultry...because at that time I was interested in breeding Black -Tailed Buff Marans and was seeing several different hues in the fancy. Danne Honour happened to be conversing in the thread and told me that this article was the best he had ever seen in descibing true Buff coloration. It's in this PDF and titled, "The Gospel of True Buff Color in Domestic Fowl. ", by W.H. Card (a noted poultryman and judge who was Danne Honours' uncle's uncle). Page 57 of 273.
