My wig started out this colour
I poured a couple drops of blue food colouring and water into a bucket. I made sure to use a blue bucket so that the dye didn't stain.
I put the wig into the bucket, swirled it around a little. I left it soak for 5ish minutes.
I left it out until it was dry.
This is the color that it turned out like. You might want to repeat step 3 again to get the color you want (:
