- "I love the fact that someone so young is so interested in our unique Hateno dyes. It is indeed part of my duty to keep the young people from losing their interest in the tradition... Let me give you all the colorful details of how the magic works! Hateno dyeing is a traditional craft of Hateno Village. In days past, we'd use our own prepared dye ingredients. But these days, there are so many monsters about, that it's difficult for us to gather ingredients... That's why we switched to the customer bringing us the dye ingredients, and in return, we have a small service charge. I can also remove color from dyed fabric so your clothes will be restored to their original, if not drab, luster."

Kochi Dye Shop is a location from The Legend of Zelda: Breath of the Wild. It is an armor dye shop located at Hateno Village in the East Necluda region of Hyrule. The shop is currently run by Sayge who uses a traditional Hateno dyeing process to dye armor and other clothing different color or remove dye from clothing.
Dying clothing is purely aesthetic and optional. Some clothing options, such as the Champion's Tunic, DLC armor like the Nintendo Switch Shirt, Majora's Mask, Midna's Helmet, Korok Mask, armor obtainable via the amiibo Rune, or head jewelry obtained from Starlight Memories cannot be dyed, the Snow Boots Link borrows from Bozai during "The Eighth Heroine" side quest (as Link can only dye or upgrade these Snow Boots until after completing "The Forgotten Sword" side quest). This is due to their fabric according to Sayge. The only Hero's Clothes armor set that can be dyed is the "Wild" set received during the "A Gift from the Monks" side quest. It is the only shop where Link can dye armor in Breath of the Wild.
In the past, the Kochi Dye Shop used its own prepared dye ingredients. But due to the number of monsters roaming Hyrule, the shop was forced to switch to having their customers bring their own dye ingredients, and in return the shop has a small service charge of 20 Rupees. The shop also provides the additional service of removing dye from clothing back into the original color. Posters on the walls show some of the materials usable to make certain dyes.
The shop is apparently well known at Gerudo Town. Saula who runs the Fashion Passion shop sells white dyed versions of the Gerudo Veil, Top and Sirwal and she even suggests to her customers to have their clothes dyed at the Kochi Dye Shop.
In order to dye clothing a specific color, Link must have the necessary materials to create a specific dye and 20 Rupees. He needs at least 5 dye ingredients (either the same ingredient or different ones as long as they apply the same selected color) to dye his armor a specific color and can dye either the whole outfit or just certain pieces. For example, Link can create a Crimson dye with materials such as Chickaloo Tree Nuts, Razorshrooms, Goron Spice, or Tireless Frogs. Some dye ingredients are rare while some or more common. Monster Parts, ore/gemstones, cooking ingredients, and Dragon Parts can be used to dye clothing. Generally, it is best to use common or easily obtainable ingredients as there is no benefit to dying making it wasteful to use of rare ingredients. There are posters on the walls of the shop that list some of the ingredients for blue, red, green, yellow, white, and black dyes. Sayge will allow Link to change his clothes before dying.
Once he has selected the dye ingredients, Sayge will drop Link and the dye ingredients he is holding into the dying vat located near the stairs and Link will walk out wearing his dyed clothes. If Link decides to restore his clothes to their original color, Sayge will drop him in the other vat. Restoring his clothes original color does not require any materials and only costs 20 Rupees.
