You can also make use of this by adding the "if" statement to detect owner only and reset on rez for builds.

        if( g_NDX > llGetListLength( realcolors ) - 1) {
            g_NDX = 0;
        }
        llSetColor( llList2Vector( realcolors, g_NDX), ALL_SIDES);
        ++g_NDX;
    }
}

and to expand even more. the tags could be simply set from ALL_SIDES to a specific side number!

    // --------------------------------------------------------------------
    timer( )
    {
        if( g_NDX > llGetListLength( realcolors ) - 1) {
            g_NDX = 0;
        }
        llSetColor( llList2Vector( realcolors, g_NDX), 2);
        ++g_NDX;
    }
}

but lets go one step further. you would want multiple sides of one prim but not all sides, simply replicate llSetColor like so.

    // --------------------------------------------------------------------
    timer( )
    {
        if( g_NDX > llGetListLength( realcolors ) - 1) {
            g_NDX = 0;
        }
        llSetColor( llList2Vector( realcolors, g_NDX), 1);
        llSetColor( llList2Vector( realcolors, g_NDX), 2);
        llSetColor( llList2Vector( realcolors, g_NDX), 3);
        ++g_NDX;
    }
}

and for those builders who like to make multiple objects sync the same color in cyclic order. the messaged link can be added to the touch event like the following. (THIS IS FOR THE MASTER/ROOT PRIM SCRIPT AND SHOULD NOT BE USED IN SLAVE/CHILD PRIM SCRIPT!)

    // --------------------------------------------------------------------
    touch_start(integer a)
    {
    if(llDetectedKey(0) == llGetOwner())
{
        // turn the timer on/off        
        g_TIMER = !g_TIMER;
        // cheeky use of flag as timer value
        llMessageLinked(LINK_SET, 0, "Touched.", NULL_KEY);
        llSetTimerEvent( g_TIMER );
}
    }

and for the child/slave prim script we would replace the touch event with a listen instead! (THIS IS FOR THE CHILD/SLAVE PRIM SCRIPT AND SHOULD NOT BE USED IN MASTER/ROOT PRIM!)

    // --------------------------------------------------------------------
link_message(integer sender_num, integer num, string str, key id)
 {
        // turn the timer on/off        
        g_TIMER = !g_TIMER;
        // cheeky use of flag as timer value
        llSetTimerEvent( g_TIMER );
    }
