Be careful about purchasing any bright yellow Turbinaria Peltata. Pagoda is naturally found in a range of colors from gray to green, but unfortunately the brightly dyed yellow specimens have been showing up pretty frequently (at least in my area). If you are referring to T. frondens or T. reniformis then yellow is a fairly common narural color.
IME frondens and reniformis can be slightly more challenging to maintain than peltata.
