I checked my facebook album to see if I have better notes, but above is all I have. I believe I used my prochem acid dyes (not jacquard as the the jacquard blue primary is really turquoise. Just the primary blue, magenta and jaquard black. I think I twisted the skein and put it in magenta and then twisted a different way and put in the blue / black. Then untwisted and added a little blue - then sprinkled sparingly with black. But honestly I could have just randomly applied color like Sarah does with a spoon and then sprinkled? In terms of the silverish color - the black in low concentrations will really deepen the blue as well as using the magenta and blue together in different concentrations. Sorry I am not more help.
