Drinking bottle reagents don't show colour.

[Mordent]

Fill a drinking bottle (from a glass recycler) with a (non-black) drink and notice how it fills with a black liquid.

Ideally, it should show things like ice like drinking glasses do (as well as be the right colour).

[HydroFloric]

This also happens with bathtubs

[Flourish]

Fixed. There's code for the ice now, too, but it's not implemented since we'd need sprites (which are kinda difficult to make look good, I think). If someone would like to give it a go, I can send you a DMI of resources.
