So I know that we are all trying to get a dark, clear buff color in our buff silkies. I am a little confused as to some of the ways people are getting there. - I have heard of people using partridge in their program. Why? Wouldn't this just add black into the mix, as well as patterning? - I have heard of a number of people that cross back to blue to deepen the buff. Why? Wouldn't this just add blue leakage into the mix? How does this get a darker buff? - Using red will also add the threat of black, but wouldn't it be a better choice to use to darken the buff? What other problems would arise from this cross? Thanks for the help!
