TX / FG: Textures and Colors in Strings Last updated August 07, 2025

In Overwatch, textures and colored text are represented by a special code known as a <TX> code and <FG> code respectively. Normally, these codes are sanitized in strings by the Workshop. This article will go over a method of bypassing this check to allow for the use of any texture / color within strings.

Implementation

The following code snippet allows for the use of a escaped < character stored in a variable. [1] 

variables {
    global:
        0: bracket
}
rule (" Setup <­tx> / <­fg> Code") {
    event {
        Ongoing - Global;
    }
    actions {
        "Script Created By Zezombye.\nMore Info: https://workshop.codes/wiki/articles/tx-reference-sheet"
        Create Dummy Bot(All Heroes, If-Then-Else(Number Of Slots(Team 1), Team 1, If-Then-Else(Number Of Slots(Team 2), Team 2, True)), False, Null, Null);
        Start Forcing Dummy Bot Name(Last Created Entity, Custom String("­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­〼", Null, Null, Null));
        Set Global Variable(bracket, String Split(First Of(Last Created Entity), Empty Array));
        Start Forcing Dummy Bot Name(Last Created Entity, Custom String("­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­ࡀ", Null, Null, Null));
        Set Global Variable(bracket, String Slice(String Replace(Custom String("­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­〼", Null, Null, Null), Global.bracket, First Of(Last Created Entity)), 63, True));
        Destroy All Dummy Bots;
        "Hello  World"
        Create HUD Text(Local Player, Custom String("{0}fgF0FF00FF>Hello {0}tx0C00000000005A0B> {0}fg00FFF0FF>World", Global.bracket, Null, Null), Null, Null, Left, Null, Color(White), Null, Null, Visible To, Visible Always);
    }
}

A rule that stores the escaped < character in a variable by using a dummy bot. A HUD Text is then created using the character as part of a <TX> and <FG> code.

Mechanism

To prevent the use of <TX> and <FG> codes, strings are sanitized in the workshop with backslashes, where < gets replaced by \<. This is how the engine distinguishes text from an actual texture. [2]

Dummy bot names have a limit of 127 bytes, and cuts off the string indiscriminately. [1] We can change the name of a dummy bot via the Start Forcing Dummy Bot Name action.

Use Cases

<TX> Codes

<tx> codes can be used in strings to show textures such as icons.
A <tx> code is in the format <tx[0C]> where [0C] is a 16 character hexadecimal string (e.g. <tx0C0000000002DD5D>).

<FG> Codes

<fg> codes can be used in strings to change the color of text (e.g. "<fg6C48C5FF>Hello World!")
A <fg> code is in the format <fg[RR][GG][BB][AA]> where [RR][GG][BB][AA] is the color in hexadecimal with four channels of color. (e.g. <fg6C48C5FF> corresponds to the color (108, 72, 197, 255) as RGBA values).

Trivia

  • This method has not been patched as of August 8, 2025 (version 2.17.1.1 - 140729).
  • <tx> and <fg> codes were originally patched to prevent abuse from players crashing the game with it. [3]
  • A similar bug appeared globally with the introduction of Season 17, where the game stopped sanitizing the codes properly. This was patched with the August 5, 2025 patch.
