Here is the collection Jacquard colors I routinely use in my studio! My primary colors come from Prochemical, but there are some Jacquard colors I use regularly: Antique Gold, Aquamarine, Avocado, Bronze, Burgundy, and Neutral Gray.
It really depends on how light or dark of a color you want to achieve, the fiber you're using, and the dye color you're using, but a 2/3 oz. jar will achieve (with rough approximation) a medium to dark color on a pound of fiber. A sample on Tencel™ and unmercerized ringspun cotton is included with each color you order.
Description from Jacquard: Use this dye for immersion dyeing, tie dye, batik, airbrushing, garment dyeing, screen printing, spatter painting gradation dyeing and more! It is a cold water fiber reactive dye, when added to tap water it is the most vivid of all dyes for cellulose fibers. It will dye all cellulose and some protein fibers. (Note: I would not recommend using on protein fibers. Alkali dyes are not suitable for animal fiber. The exception is silk, but the final color may not be what is expected.) This package contains a 2/3oz jar of dye. Powder solution changes color when adding water. Final result matches bottle label. Available in a variety of colors, each sold separately. Conforms to ASTM D 4236. Made in USA.
