I personally love acid dyes, but I hear so many people say that they're terrified of them. I swear that they're not as scary as you think, but if you still feel that way just stick with kool aid dyeing. The reason that so many people find acid dyes so scary, in my mind at least, is due to the fact that acid dyes can not be used in anything that may be used for food or cooking. Which is a valid reason to avoid using them, but there are solutions to this. I actually use either old paint brush when I dye, when are those every going to come in contact with food, or an old crock pot. Typically I either use the crock pot for single color dyeing or to soak the fiber with vinegar in. That's also the reason why it's called acid dye, vinegar is used to set the dye into place. Acid dyes also provide a wide array of different colors where you can have more control over the intensity of the color. While I've found with kool aid dyeing that it produces a more pastel effect, which can be the exact color you had in mind. If you would like to use acid dyes I'd go with Jacquard acid dyes. I've tried a few others where the colors appear nice, but either have a coarse texture or don't produce as intense of a color.
