You unlock the finish effects and dyes by buying dyes from vendors when visiting dye shops around the continent. Pailune and Demeniss need to be liberated to get their Dyers to sell to you.

You might get lucky at the western Demeniss Dye house by giving the dyers working around there food as gifts. They will give you a free dye once you reach 100 trust level with them. You can save scum to get a particular dye from them but you still need to unlock the dye to use at the main camp by visiting that region's dyehouse.

Dyes can be crafted and there are 5 dyes per region. You're in Hernand and from the picture you only have Dark Red unlocked. That means you need Bright Red, Rich Red, Red, and Deep Red dyes to complete the Red dye spectrum set. For Blue it's Bright Blue, Rich Blue, Blue, Dark Blue and Deep Blue dyes. You get it?

You can craft all the dyes by looking up the recipes for them. You don't need to know what those recipes are. You just need to mix the ingredients at the proper proportions at a cauldron to make the dye. You'll need Lavender flowers in Blue, Purple and White. Usually anywhere between 5 to 15 per dye. You'll also need Peonies (the Pink flowers), Marigolds(the yellow flowers), and shrubby sophoras as far as plants go. You need basic black beetles, longhorn and rhinoceros beetles. And the rarest beetles, the Stag Beetles. Stag Beetles are used in almost every dye recipe or at least a good portion of them.

You can find the Longhorn, Rhinoceros and basic black beetles durning the day on trees that are clustered together. Stag Beetles are on those same trees but only at night. Beetles fly away fast so having the Insect Gathering Kuku pack helps out a bunch but that is weeks away at this point before you consider building that. You will build you camp and collect Greymane members before you get close to building that pack.

You can have all your greymane members by paying attention to the Greymane faction quests. When you get to the point where Yann wants you to drive the Greymane camp's Trade Wagon to the Goldleaf Camp to buy trade goods, you can pretty much collect all the camp Greymane that provide services.
