Yellow feathers, along with all coloured feathers gathered from the Hunter skill, can be used in place of regular white feathers for the Fletching skill. Despite the difference, the bolts and arrows created still come out with white feathers and have no extra properties. They are colourful and can be sold at the VarrockFancy Dress Shop for 3 coins each. However, unlike white feathers, they can not be used for Fishing.
Yellow feathers were originally orange feathers; however, at some point, brown feathers were renamed to orange feathers. To avoid confusion, the feathers obtained from golden warblers were renamed to yellow feathers.
