That's a choice one Tim - I have quite a few and can tell you that not all of them have nicely colored new leafs. So that's why yours is cool. One other thing I can tell you is that if you see any orange on the older fronds, it is lacking potassium.
At least here in Hawaii they are always potassium deficient unless some K-Mag or other supplement is used. For some reason, these palms get real orange around the edges when craving potassium, and then the typical "dotting" kicks in - both a very bright orange color.
