The downside of a script is, that it needs to execute on the server: you need to have the proper syntax for the shell of your operating system.
Here's a little example for a bash shell script, just to give you an idea (that would be for Linux, I have no experience with Windows):

Allow HTML = 1
Attributes =  person, mood, color
Default encoding = 2
Options person = John, Bill, Kate
Options mood = calm, upset
Subst color = $shell(if [ "$mood" == "calm" ] ;then echo "green"; else echo "red";fi)
Change person = <font color="$color">$person</font>
List Change person = <font color="$color">$person</font>
Show Attributes = person, mood
Show Attributes Edit = person, mood
List display = ID, Date, person
