However, I get change the font color, type, or the pink background.

.jetpack_subscription_widget {
clear: both;
background-color: #FFFFFF;
padding: 32px 40px 24px !important;
padding: 3.2rem, 4.0rem, 2.4rem;
font-size: 18px;
color: #000000 !important;
}
.jetpack_subscription_widget input[type="email"] {
  border: 1px solid #999999;
  padding: 7px !important;
  font-family: "Lucida Console", Georgia, Sans-serif;
  font-weight: bold;
}
