I'm shooting for a true red. A nice, simple, no doubt about it, red. Today I added black and still couldn't shake the pink tint. Last time the black worked for me, but like I said I didn't write it down. On the other colors I only use like 2-3 drops per pound on average, depending on the color of course. How many drops per lb of the concentrated dye can you get away with? Maybe I'm just not using enough.
