Strange

Strange quality is an item quality found on cosmetic items obtained from unlocking Treasure Chests of certain series. Introduced in the DotA 2 Update on May 31st, 2012 Patch, Strange items track victories, or other hero specific characteristics such as kills or trees created, and record them as an item attribute, allowing the count to be viewed by players.

The DotA 2 concept follows the trend of Team Fortress 2, the item is awarded a rank as the stat recorded count increases, with the rank affixed to the beginning of the item's name.

The hexadecimal color code for Strange items is.

General Ranks
Stranges rank up based on the number of tracked stats. At each new rank, the prefix of the Strange will change to its respective rank. For example: An Unremarkable ranked Vile Carnival Hat will have its name changed from "Strange Vile Carnival Hat" to "Unremarkable Vile Carnival Hat".

Special Ranks
Nature's Prophet and Juggernaut Strange items have special ranks for hero-specific abilities such as "Treants/Trees Created" and "Omnislash Jumps".
