Form's field changing color

[Aetius]

Hello!

I have been trying to change the color of the fields in a form I created. What I want is to have a certain color in the field but the moment someone start filling the form, the color turns to white, making the font much more visible. I  have until now not not been able to do it, and the instructions offered by Nitro have not helped me much. I wrote to AllainU who has helped me in the past about this issue but he seems to be non responsive. I hope the sanitary emergency has nothing to do with it.

Any help would be highly appreciated.
