<!--- to use this example, create a color.cfc component as follows: --->
<!--- 
<cfcomponent>
    <cffunction name="myFunction" access="public" returntype="string">
        <!--- Create a structure object --->
      <cfset myColor = "Blue">
      <cfreturn myColor>
    </cffunction>
</cfcomponent>
--->

<!--- Create an instance of the color.cfc component --->
<cfobject name="getColor" component="color">

<cfif IsObject(getColor)>
   <!--- Invoke the myFunction method --->
   <cfinvoke
      component="#getColor#"
      method="myFunction"
      returnVariable="myColor">
   </cfinvoke>

   <cfif IsDefined("myColor")>
      <!--- Output the returned variable --->
      The value of myColor = <cfoutput>#myColor#</cfoutput><p>
   </cfif>
</cfif>
