Tritium dial experts - need your explanation pls!

So I purchased a PAM 243 J series with T Dial a while ago and I immediately noticed that the luminence in the hands and the numbers 12 and 6 were slightly whiter/greener than the dot markers. The dot markers already has some patina and looks like more like a creamy white.

Can anyone explain why this is? Did Panerai use Tritium in the dot markers and Superluminova in the 12, 6 markers and the hands or is it that the patina is developing at different rates?

I've also wondered this, it happens on a lot of subs.

It's to do with the fact that the hands allow some light through as the skeleton hands have no backing. The numbers and dots however have the blackness pf the dial behind then and allow no light through. Just a thought.

Yes but the 12 and 6 have the backing of the dial too

So the 12 and 6 should look the same as the dot markers too then?!

Tritium oxidates more rapidly when it comes in contact with metal >>>

The dots are little metal buckets, the 12 & 6 numerals are not surrounded with metal, but rather lay on a bed of paint, hence the dots oxidate faster then the numerals.
