Similar to how you can "fast travel" by right clicking travel on shippers, vs talking and clicking after the conversation, Should make it so you can right click, use say Onion (have 2 in inventory + coin cost) on Aggie and she makes the color, same for redberries and woad leafs.

Or when right clicking her have 3 options, make yellow, make red, make blue

Takes a while when you gotta make a bunch for doing clues.

Edit.

Another one is having a "fast" travel for the tree gnome village, just skip all the pleasantries and right click, travel and you're off.
