Carpet dying takes practice and patience. With time you will develop an eye for the color. First, when dealing with bleach, make sure to neutralize the bleach COMPLETELY or the dye will not take (learned this the hard way). It will look great day-one but the color will fade within a day or two. Add a little color at a time so that you don’t over-color and go too dark. A hair dryer comes in handy to dry the dyed carpet in between coats so that you can get a better look at the “final” dry color.
I’ve been at this for a year now and I’m still working on getting a job to match perfectly. I typically get anywhere between a 80 to 90% match and my clients are usually thrilled with the results.
Yes – a final misting with the color set will do the trick.
