White tea does not undergo the "killgreen" step that green teas and oolongs teas do IIRC. The drying slows the oxidation but does not arrest it. "Aged" white tea is a thing. If you let it sit around long enough it turns deep red. Green tea just turns into stale tea. They even compress white teas into something similar to those "Pu'er Cakes".
