how to set a gradient color along with a Hair strand.

Instruct how to set a gradient color along with a Hair strand.
And also how to use V-Ray Hair Variation Texture.

Isn't there any simple example?

See attached scene, make sure to enable Use Render Cache in the V-Ray Preferences.
Basically the Driver A effect is used to pipe the gray hair variation color through a gradient.

I will eventually add a gradient control right inside the hair variation texture.
