Mailchimp Plugin

Hi,
I have installed the Mailchimp Plugin.

Unfortunately I’m hvaing trouble formatting the form. It is at the bottom of the website below.

Does anyone know how I can change the text AND BACKGROUND COLOUR colour please?

I would like the E-Mail address/First Name titles to be blue and the background to be white. Then I would like the input boxes to be black.

Thanks for any help.
