I wonder if there's some proven recipe published for black made from basic/pure dyes.
I always mix it - on the fly - and sometimes it comes out OK, sometimes it turns out to be either browny or greenish or greyish.
I know that this has been discussed several times. If I understood it well, higher concentration was also important issue.
I'll apreciate any shared experience in this field.
(I've just made commitment to myself, that next time I'll premix black as accurate as I can)
PS: Paula knows that I have only six basic colors...
