From your photo it looks like you got a decent dark gray, wine, and a dark purple. I've had problems getting a nice deep black, but have ended up with some very nice gray shades in my attempts, which I like for backs when tying baitfish streamer flies. Some of the dark gray is fine as a black too, but when I want a deep jet black now, I just buy them already dyed.
I've found it takes a lot of dye for me to get a good black, and frankly for the prices of deer tails that I buy most, not worth the effort or cost to me.
That wine color you got there would be great for bucktails for Stripers!
Like you I don't get too concerned if colors don't turn out as I want, as anything I end up with I'll use.
I haven't tied any of those Manic Mullet heads yet with hair, but I have a couple on my desk now that I intend to do just that. I painted a few white, so that's what I'll be tying. Like you, I'm looking forward to trying them.
