Add support for hint text color when locked in

[ursusursus]

When using DotDocument, one can customize text color when both candidates are generating and not (2 colors)

However, when using FaceAutoCapture, I can only specify a single hint text color

Which then clashes with our brand colors

(What I need is black text on white background when not locked in, and white text on blue background when locked in)

please take a look at this, we're about to hit production
