===== Red Example =====

<code bash>
echo -e "\033[0;31mThis is in RED"
</code>

<WRAP info>
**NOTE:**  This is made up of:

  * **<nowiki>\033</nowiki>** - Represents the ESC key.
  * **<nowiki>[0;</nowiki>** - Normal color.
  * **<nowiki>[31m]</nowiki>** - Red; from color table.
</WRAP>


----

===== Bright Red Example =====

<code bash>
echo -e "\033[1;31mThis is in BRIGHT RED"
</code>

----

<WRAP info>
**NOTE:**  This is made up of:

  * **<nowiki>\033</nowiki>** - Represents the ESC key.
  * **<nowiki>[1;</nowiki>** - Bright color.
  * **<nowiki>[31m]</nowiki>** - Red; from color table.  Notice this is NOT using the bright numbers from the color table.

Bright colors can be used simply by using a **1** after the ESC instead of a **0**.

  * Some older systems may not support this, so in this case use the alternative number from the color table; 

<code bash>
echo -e "\033[0;91mThis is in BRIGHT RED"
</code>

  * Here the **31m** has been changed to **91m**.

</WRAP>
