When it comes to wig choices for cosplayers, Arda Wigs has a wide selection. I’ve used a few of their products and been pleased with the quality and price. However, the wigs have heat resistant fibers which can make them tricky to dye – and sometimes dyeing is a necessity to get the proper shade. Sharpie markers or ink based dyes will rub off. DeviantArt user Malindachan, a.k.a., Malinda Mathis works with Arda Wigs and shows how you can use fabric dye to alter the color of Arda Wigs.

You can use iDye Poly or RIT in liquid and powder varieties. The basics: boil water in a large pot (preferably one you’re not using for food), add the dye, and add the wig. Different amounts of time alter the depth and richness of the new color. You should always dye a sample first before throwing the entire wig in.

Some example swatches:
