Fixed and corrected!
Evelwyn can create some dyes. This is what they are and need. They all generally need over 2 silver in items from vendors. Chalk or dye salts, water, and small glass phials. She can also do the farming for the dyes. (Need extra silver to purchase the soil to try and crit it, along with buying seeds, fertilizer and water.)
Tier 1: (Uses Clouded eyes (from spiders) to crit. Can give her those instead of some extra silver)
Gold Dye:
Yarrow Root (Found in the beginner areas: Ered Luin, Shire, Bree)
Sienna Dye:

Wall colors: (Don't have a crit option)
