Message: Is less dye required to dye black from a very dark grey? I have chosen Dylon Permanent Fabric Dye, Velvet Black to dye a pair of mens trousers. They are 100% cotton and weigh 1 1/4 lbs.(550 grams). Thank you for taking my question.

In general it does take less dye to color over an almost-dark-enough color, but I would use the full amount anyway. It is hard to reach a full deep black, so it's best to use a lot of dye.

It's a good idea to use at least two packets of Dylon Permanent dye for a one-pound garment.

Be sure to pre-wash the trousers thoroughly in the hottest water they can tolerate. It's disappointing when a previously invisible stain shows up after dyeing as a lighter spot on the fabric.
