Comment on Tutorial: RIT-Dye Color Chart by taeliac

Hrm... I actually do not know! I've heard that bottom weight doesn't take to the dye very well, for darker colors (my friend tried to ombre dye some for her final, and it came out lighter than she wanted, but that was using a fiber reactive dye, not RIT). You may either need to dye it a couple of times to get it dark enough, but I do know that it's possible to get the color onto the fabric

Your best bet is to do a small sample of it (just scale down the proportions of water and dye) and see what color it comes out. Before dumping all of your fabric into it, though, let the dyed sample dry overnight, and then rise it out to get all of the dye out of it That should tell you if you're going to need to do it more that once!

You may also want to experiment with using a darker blue in conjunction with the aquamarine dye, but that is definitely something to do samples with before dying any quantity of fabric
