VBA - How to change field text color in a PDF form?

I'm using .GetField("").Value to change the text value, .GetField("").textSize to change the font size, and I'm pretty sure there has to be more commands to change the rest of the values, like color, bold, italics, underline, etc.
I would be so grateful if someone knows these commands and shares them with us.
Thank you!

I think the background and text colour properties are .FillColor and .StrokeColor, respectively.

Thank you!!
