You are either gonna like this or hate it, but please note a couple of things. 
 
1. Try to use a soft colour (like a pastel) they are easier on the eyes

 
2. Some people do not like colours in chats so you may end up being put on ignore if you abuse it. 

 
Step1



Within game 

type the following command

/alias d c dragon <!--color r=0.5 g=0.5 b=1>

/saveui



This creates the new alias command



Close down horizons



Step2



Open windows explorer and goto the following location



c:\program files\artifact entertainment\horizons\prefs\chaos_chasing\UICommu nicationPrefs.def



Open this file in notepad



Scroll down to the bottom of the file.



Amend the alias command entry to the following



ALIAS

{

string Long = "c dragon <!--color r=0.5 g=0.5 b=1>"

string Short = "d"

}



Save the file



NB. There is tab formatting within the file, probably best to leave the formatting as it is



Reload Horizons on the same character.



Type /d test



And watch the result in dragon chat



NB for market



/alias m c marketplace <!--color r=0.5 g=0.5 b=1>

/saveui



NB to change the colours you have to edit offline directly into the DEF file doing it in client does not work



NB type

/alias d



to delete the alias command
