Rarity

Rarity is usually considered as a measure of how difficult to obtain or how valuable an item is. The color of the item name text indicates the rarity of an item, with White being the least rare and Cyan being the most rare. Any item with the rarity of White or Gray will be destroyed upon contact with lava (excepting only Obsidian, Clay Pots, Living Fire Blocks, Fireblossom, and Fireblossom Seeds).

It should be noted that the rarity of many items can change significantly depending on their modifiers.

{| class="terraria" style="width:100%" ! Tier ! Color ! Description
 * style="color:gray;"| Gray
 * This tier consists entirely of low-tier equipment with poor modifiers, such as a "Shameful Iron Broadsword", and the 'junk' items Tin Can, Old Shoe, and Seaweed which can be caught from fishing. This is the lowest possible tier.
 * 0
 * style="color:#999;"| White
 * All basic items, such as the Copper Pickaxe, fall under this category. These are mostly building materials. Items that are white are not necessarily worthless, but could be a good source of income early on. Items from this tier will be destroyed in lava, unlike the higher tiers, with a few exceptions.
 * 1
 * style="color:blue;"| Blue
 * Weapons and armor made of early game ores are tier one. Certain accessories such as Shackle and Lucky Horseshoe are also Blue. Certain non-craftable weapons, such as the Ball O' Hurt, and most accessories are Blue. Mid-game items with poor modifier, such as "Shoddy Fiery Greatsword are Blue rarity. Items in this tier and above cannot be destroyed by lava.
 * 2
 * style="color:green;"| Green
 * These items are largely non-craftable, with the exception of Necro armor, Sandgun, Sunglasses, Obsidian Skull, and the Star Cannon. Muramasa and the Harpoon as well as spells like Water Bolt are Green. The Wizard Hat also falls under this category.
 * 3
 * style="color:rgb(220,120,0);"| Orange
 * Weapons and armor made of Hellstone, jungle-related equipment and items found in chests in Underground Jungle or Underworld are Orange. Certain non-craftable weapons and accessories are Orange, such as the Staff of Regrowth, Rocket Boots, Feral Claws, Flower of Fire, and the Dark Lance. Early Hardmode ores and materials also fall in this category.
 * 4
 * style="color:red;"| Red
 * This is the base rarity for many hardmode items, such as items forged from the hardmode ores.
 * 5
 * style="color:fuchsia;"| Magenta
 * Magenta is the base rarity of rare and powerful hardmode items, such as the Flamethrower or the Dao of Pow. Most of these items are crafted out of rare early Hardmode drops and mid-game materials. This is the approximate level of Mechanical Boss tiered items.
