I bought a lovely lot of acid dyes from a mama on the Wooly Wonder Forum. Yesterday afternoon during Abigail's nap, I pulled them out, wound up a bunch of small hanks, and did some test dyeing. I recorded the dye color, amount used, quantity of water, and amount of citric acid used on big index cards like this for future reference:
Here are each of the colors in light, medium, and dark shades. On a couple of the colors I might even do a pale card. I used mini measuring spoons (nip, dash, pinch, etc) that I bought at Linens N Things along with a 1/4 tsp. My method of mixing wasn't very scientific but it was standard across the board so I will easily be able to reproduce each color in the future.
Brilliant Blue
Brown
Burnt Orange
Purple
Spruce
Chartreuse
Fuschia (this is the LIGHT shade)
And here they are all hanging out together:
