Lua question - Animated text tfs 1.1

[FLE]

So I have a quick question..

Is it possible too make get.spectator see by TEXTCOLOR_ ?

because I see here im using zbizus wild growth and mwall scripts and he uses TEXTCOLOR_ for the timers...
here is the his script- tile_timer(id,pos,40,TEXTCOLOR_LIGHTGREEN)

local id = ITEM_WILDGROWTH
local combat = Combat()
combat:setParameter(COMBAT_PARAM_DISTANCEEFFECT, CONST_ANI_EARTH)
combat:setParameter(COMBAT_PARAM_CREATEITEM, id)

function onCastSpell(creature, var, isHotkey)
    local c = combat:execute(creature, var)
    if c then
        local pos = variantToPosition(var)
        addEvent(removeMw, 40000, pos, id)
        tile_timer(id, pos, 40, TEXTCOLOR_LIGHTGREEN)
    end
    return c
end

Can we make animated text using these TEXTCOLORS?

please explain if possible,

Thanks,
-Martin
