customizing button and the form in general

Hello again, is it possible to change the look and feel of the widget form. For instance, changing the color of the subscribe button. Or have a background color, and so on?

If yes, where can I make those changes.

I’m migrating from BLOOM and mailchimp and I’d like, as much as possible, to keep the same look in design… Well try to make something aesthetically pleasing.

Many thanks

Pat
