Amethyst" and hues more on the purple/red side of the spectrum.
Regardless of the cultivar, because they flower int he late fall mid winter range they're almost exclusively pollinated by flies. There are reports of honeybees working them too and I'm sure dozens of other little insects that over winter in the adult stage. These insects all require warm days above 45F in order to function, that's also when Witch Hazel plants produce a faint fragrance to attract them.
I'll be keeping my eyes out for any pollinators on our shrub. It's still fairly little though so I'm not expecting to get much.
Hope your winter is going well.
