Android Material TextInputLayout hint/label colors

Question

I have a material TextInputLayout and am trying to make the hint a different colour when the input is in an "empty resting state", where the hint is shown as a placeholder, than when in a "filled resting state", when the text is shown as a label in the upper left (I'm using outline view).

I have to do this programmatically, I can't use styles (the colors are dynamic and are coming from a server at runtime).

I can get a different color when the edittext has focus, but cannot figure out how to get a different color for the filled/empty non-focused states.

Is this just not possible?

On a related topic, I cannot figure out the difference between: et.setHintTextColor(csl); et.setDefaultHintTextColor(csl);

And then there's a .setPlaceholderTextColor(csl) that doesn't seem to do anything!

To me, it would make sense for one of these to control the "label" and another the "hint".
