To quote DyeYourYarn.com, "...if you want a hank of solid black wool - just go ahead and buy one. It is very difficult to dye large amounts of yarn a true black."
And there is a very good reason for this, if you are dyeing with food safe colours. It is because there is no such thing as a true black food colouring. Black food colouring is actually a blend of a lot of other colours, and has a tendency to lean more towards one colour or the other. In the blacks I have worked with, the colours tend to be either more green or more red than I had anticipated.
Part of this has to do with the way the dyes strike on the yarn. As I think I have mentioned in a previous post, reds will strike faster than blues, which can mean you get more of a reddish tinge to the yarn. And black has a tendency to "break" when you use it to dye yarn, meaning the various colours not only strike a different times, but tend to actually separate on the yarn. This is a great effect if that is what you are going for, but can be a pain in the butt if you are trying for a solid colour.
I have used black a few times in the past as an accent colour. The first time I used it was in combination with some pink. It did give me a dark colour, which looks nice next to the pink, but it is a bit lighter than a black in person, and in one or two spots, looks a bit closer to an extremely dark brown. I don't remember what I used for this one, as this was back when I was not taking very good notes. I THINK this was the new "non-breaking" black from Wilton's. Their old formula broke really easily, while the new one seems to hold together a bit better.

|Bigger section of the yarn dyed black. You can see that it has a reddish tinge to it, and can see a few spots where the dye did not really strike, and there are light almost blue sections|
|That yarn above resulted in this sock. Looks like black stripes to me. As long as you don't look too close|
|A swatch of the yarn above. I have not knit up socks with it yet.|
I will post again either later today or tomorrow with the results from my full skein of black!
