I used this powder pink color on a white silk chiffon long dress out very very light pink, I should have put two ... (I used one box of dye and a box of 500 grams of salt fixative.) Easy to use, poured dye bag in the drum and then the salt and placed over the machine (wet back) and washed with 40 degrees. When finished, you must restart a machine at 40 degrees with detergent to wash clothes complexion. Then restart a last empty machine with detergent to wash the drum (for traces of dark paint) because with powder pink, I do not need to do that
