changing color attributes in input fields

Hey, i was just curious as to how to change the color of an imput field (such as the one you would type in if u were to submit a reply to this). i have an imput box for people to sign up for a mailing list, but the box doesn’t really fit in with the rest of the design, so i’d like to change the colors of the box.

any help is much appreciated. thanks.
