The Salvia hians I grew once, from seed obtained from P. Kohli & Sons in Srinagar, India, had the color of that in your images, and was two-toned, with a bluish-purple tube and a purer shade of blue for the lower lip. The flower was quite large, big enough to admit a bumblebee, about 1.2 cm wide and 2.5 cm long.

S. przewalskii is a lot smaller, and very variable. It does better for me in subtropical North Carolina.

Lots of salvia flowers show the feature of the exterior backside of the lips being a different color, usually with less pigment. The part of the flower hiding inside of the calyx usually lacks pigment as well, but not always.

Cait,

That's an awesome salvia, if you get spare seeds I'd be first in line to trade. Thanks for sharing the pictures!
