Nichia 219B comes in so many different variations. The tint might be affected by the driver, reflector, lens or optic used.

Anecdotally, the Nichia 219B sw45k D200 that I bought from @Bob_McBob and swapped into a Wurkkos WK01 looks too rosy for my liking.
On the other hand, a Nichia 219B sw45k D220 looks pretty neutral in a ReyLight Pineapple Mini [comparison].
I personally prefer a beam that is close to neutral.
