You should be able to customize the look of the form with custom CSS. You can add that custom CSS to your theme stylesheet, or to your custom CSS editor under Appearance > Edit CSS in your dashboard.
If you’re not familiar with CSS, I’m happy to help you figure out what CSS to use. However, I can’t seem to find the subscription form on your site. Could you let me know where it is?
Thanks!
Jeremy, the Happiness Engineer, Herve ~ I am not familiar with CSS so would love some guidance. The site was closed for maintenance but has since been opened and so you can have a look at where the subscription form is located at http://www.timscottphotography.com/blog
Thank you

You can use that custom CSS:
.inner .jetpack_subscription_widget input {
background-color: rgba(255, 255, 255, .2);
color: #fff;
-webkit-transition: background-color .125s ease-in;
-moz-transition: background-color .125s ease-in;
-o-transition: background-color .125s ease-in;
-ms-transition: background-color .125s ease-in;
transition: background-color .125s ease-in;
}
.inner .jetpack_subscription_widget input[type="submit"] {
padding: 5px;
background: #fff;
color: #000;
border: 1px solid rgba(255, 255, 255, .2);
}
