Thanks, yes it's the Hue light - as sibling comment pointed out, I dragged in the app name for one that controls them.
And I have two, one above to the rear right and another to the rear left doing exactly what you describe.

(As an example, a hair light is an overhead light that’s typically used to give hair more depth and detail. The poster talks about a key light, which is the strongest light in a standard 3 light setup)
I imagine ihue is the brand of light. Or maybe just a misspelling of Hue’s brand.
