I think your observations are very interesting,
bjostone! I'm certainly no expert on H pinks either - for years I only wore blues....
In the last year or so it does seem that there have been more pinks that are either brighter fuchsia or more coral, than truly pink? I don't see that many shawls in person so would love to hear more from anyone interested.
Here's an old thread from 2008 with a bunch of various pinks:

For fun here's a collage of 'pink' cashmere shawls that I had pics of, some more successful than others. Cooler, fuchsia pinks don't work, nor do the slightly grayed or browned old rose pinks. :cry:
****Note, I never had all of these at once, it was a gradual process as I figured out what worked.***
Row 1:
Sorry, the pale baby pink Kachinas came up twice to balance out the grid! But it's a favorite.

Tendresse Feline - very warm, peachy pink.
Marwari - a bit dull. old rose pink.
Les Danses des Indiens - soft warm pink, incredibly flattering.
Cavalcadour - really flattering pink coral, very close to Rose Jaipur
Row 2:
Tropiques - great deeper coral pink.
Grands Fonds - towards fuchsia for the border, Bougainvillea warm pink interior makes it work. (plus turquoise.

)
Paperoles - true pinky pink.
Kente - pink with some lavender.
La Femme aux Semelles du Vent - border old rose with a touch of brown in it? Pretty peony pink in the border.
Row 3:
Carre en Carres - left section is Bougainvillea pink again, pale rose pink for the BdeG interior.
Lujo Criollo - stronger bright fuchsia pinks.
Marwari - Rose Indien, intense and fuchsia.
Parures des Maharajas - same.
