Vial of Dye

Basics
A Vial of Dye (usually just called Dye for short) can be used to change the color of Items.

Dye comes in the following colors:

Usage
You use Dye by double-clicking on the Vial of Dye, and then clicking on item you want to dye.

This will then bring up a window where 1-4 dyes can be placed to make a certain dye color. Backpacks, belt pouches and bags will be dyed immediately without a preview window.

Most armor and weapons can be dyed, though the effects vary among different equipment. Using the same dye on different armors can look very different. It is advised that you use the dye preview panel to examine the resulting color before applying the dye.

Some items dye differently from normal, such as the Chaos Axe, Necromancer Ascended Scar Pattern Armor, and female Monk Obsidian Armor (you can find guides for dying these at the Guild Wars Guru and OGaming links at the bottom of this article). For example, using blue dye on a Chaos Axe will turn it red.

Dye added to armor and weapons can be removed using Vial of Dye (Gray). However, it is not necessary to remove dye when changing from one color to another (for example, if you have armor that has been dyed red, you do not need to remove the red dye before dying it green.)

Note that some weapons and armor (such as Eternal Shields and Elementalist Headgear) cannot be dyed. Also, some items, such as the Eternal Bow and the Necromancer Ascended Scar Pattern Armor, will accept dye but do not change noticibly when dyed.

Dye can be obtained by looting slain enemies, buying them from Dye Traders or trading them with other players.

Silver will not make non-metallic parts of the armor shine. For example, the Elementalist Ascended Aeromancer's Armor is dyed only in the cloth non-metallic parts. The shiny lightning is always white. Dying the set silver will make the cloth parts a light grey as opposed to silver.

Dye can also be used on bags. This doesn't affect the character's outward appearance, it just changes the bags' color in the inventory window. The dye preview panel does not appear for bags.

Mixing Guild Wars Armor Colors
You can mix dye effects in the dye preview screen by simply dragging the dyes you wish to mix into the appropriate slots. Once you have the color you want click apply and the mix is applied directly to your armor. You no longer can mix dyes together to create a "Mixed Dye". Colors can be mixed only in the Dye Preview window, which then is only mixed when applied to the armor.

You can also use grey in dye mixes; in this case the remover acts as the base color of the item the dye is applied to. For example, if you mixed a grey dye and a green dye and applied it to a Necromancer armor (base color Red), the resulting color would look the same as if you had applied a Red + Green mix. Each class's armor has a base color, as follows: Warrior = Yellow, Monk = White, Ranger = Tan, Necromancer = Red, Elementalist = Purple, Mesmer = Green, Assassin = Blue, Ritualist = Orange (Update as of 10/26/2006 - "Newly crafted armor now starts out gray. If you dye it to another color and then later want to restore it to its original appearance, just dye it gray. Vendors now sell gray dye instead of dye remover."

You can also see All dye combinations. (some combinations may be inaccurate)

Some general tips for mixing dyes:
 * Mixing Silver with another color produces a dull metallic version of that color. More specifically, adding silver dye in a mix increases contrast and decreases saturation.
 * Yellow + Blue usually makes a dirty yellow, although on some metallic armors it comes out as light blue.
 * Orange + Green generally makes a light brown color on cloth armor, or a rusty brown on metallic armor.
 * Red + Green makes a nice orangish bronze on some armors, and a dark brown on others.
 * Yellow + Purple makes a brown color, slightly lighter than the official brown dye you can choose for your armor when you make a new character. This combination very closely resembles the official brown dye on cloth-based armors, such as Assassin, Ranger, and Monk. It also makes a nearly official red dye color on metallic armors.
 * Red + Blue makes lighter purple than the purple

Dye Notes

 * Dye behaves differently depending on the type of armor it is applied to. For some, applying black dye will turn the armor into a dark purplish color. Others may result in more of a dark gray. Before accepting to dye your armor, you may want to consider trying combinations inside of the preview window, to get a more desirable look for your character.
 * Dye is a somewhat valuable commodity, and as such is sometimes a target for farming. It is commonly believed that dye drops more frequently in pre-Searing. For more information on farming dye in pre-Searing, read the Green Hills County dye farming guide or Bandit Raid Dye Farming (Pre Searing). Also, in Wizards Folly (Pre-Searing), the Hulking Stone Elementals and Stone Elementals drop quite a few vials of Dyes as well.
 * Black dye or White dye are very rare drops. These have the obvious effects of increasing the market value of their specific vials of dye. New players are often unaware of this fact and occasionally fall prey to scammers (see dye scams for details).
 * Silver dye has the same drop rate as all other dyes except for black or white. However, its market price is generally higher than other non-high-end dyes because it is more sought after. Recently the prices for silver dye have dropped substantially due to the inclusion of grey dye.
 * Since the release of Nightfall, when you put a dye on your armor, a Dye Preview panel will open that allows you to see what your dye will look like on that armor, along with other items such as weapons, shields, bags, or even the end result of dye mixes.
 * The same colored dyes can be mixed together alone to get a deeper color. For example, by mixing two black dyes you will get a deeper black color than if you just do one black.

Buying and Selling Dye

 * If you want to make more gold off dye, don't sell to a trader. Simply check what the trader charges for the color you want to sell and lower the price a bit. (for example, say red is going for 600g, charge someone else 550g) You will make more gold that you may need.
 * Note: Do not buy gray dye from anyone for more than 50 gold. Scammers often try selling it for 1 platinum. Do not trade with those people. You can get gray dye for 50 gold at any merchant.
 * Always check the current prices at traders before selling to players.
 * WARNING: Hover over the dye in the trade window before accepting, as some dye colours can be mistaken for others, such as silver for grey. This is a popular scam players use.
