Dyed Armor

Before the 0.7.4 Update November 11, 2019, players were able to use dyes, of any color, to color any Armor of their choice. Now that dyed Armor became unobtainable, the price of still existing pieces is skyrocketing. Therefore, prices can be upwards of millions of for a single piece of the armor to billions of  for a full set.

After the 0.12.3 Update March 1, 2022, players could once again dye Armor, but restricted to the 23 different Dye colors. So the Armor pieces would appear different to exotics, there is an icon next to the item's name and the color of the Dye in the description.

Dyeing Armor was still possible, but only with Crystal and Fairy Armor. Armor pieces with Crystal/Fairy Armor colors are worth less than normal dyed armour but still has value, and are collected.

NOTE: It is no longer possible to dye armor, as Dyeing with Crystal and Fairy armor was patched.

NOTE: Even though Armors like Yellow Shark Scale Armor are not dyed originally, they are still expensive as they were obtainable through normally crafting upon release of the Armor, which is no longer obtainable.

Hex Codes
In order to check the color of an Armor piece, you need to check the Hex Code. Using the hotkeys F3 + H, the player can enable the formatting code which makes Hex Codes visible (not relevant on versions 1.16.2+).

Rarity
Some dyed armor pieces are more rare than others, this is solely due to the quantity of dyed armor pieces and colors.

This is an estimate of dyed armor and how many pieces may exist (in alphabetical order):


 * Armor of Magma: 15,000
 * Angler Armor: 3,000
 * Bat Person Armor: 25
 * Blaze: 63
 * Cactus Armor: 50
 * Emerald: 580
 * Farm Suit: 300
 * Guardian Chestplate: 800
 * Lapis Armor: 8,000
 * Leaflet Armor: 75
 * Mushroom Armor: 800
 * Necron's Chestplate: 3
 * Obsidian Chestplate : 1,300
 * Old Dragon Armor: 2,600
 * Protector Dragon Armor: 2,200
 * Pumpkin Armor: 50
 * Speedster Armor: 1,200
 * Squid Boots: 75
 * Stereo: 300
 * Strong Dragon Armor: 5,800
 * Superior Dragon Armor: 1,450
 * Tarantula Armor: 150
 * Wise Dragon Armor: 2,200
 * Young Dragon Armor: 3,300

NOTE: Green, Mint, and Blue appear to be the more expensive colors. However, Yellow is a very common color for dyed armor because many players used to dye their armor to recreate a fake Superior Dragon Armor set. Additionally colors that are very similar to the Fairy/Crystal armor sets are also less expensive.

Prices
The cheapest sets are Armor of Magma sets and most Dragon sets, except Superior Dragon Armor due to their availability. These sets can go for around 8-30 million coins.

The more "exotic" the color, the more people will pay for it. Example: if it's a Lime Green, or a Light Blue, full sets of certain armors, like Superior Dragon Armor, can go for hundreds of millions.

Fully-dyed 'exotic' Tarantula Armor sets can go for upwards of 1 billion coins

Example of rarity comparison: Green Young Dragon Armor is way more expensive because of the color, compared to Black or White Young Dragon Armor.
