To change the background color of the Header elements, you can add the next CSS to the form:

.form-header-group {
background-color: #ffffff;
}

You can also change the Font Family and Font Size from the same tab:

If you would like to remove the 'italic' font style of sub-labels, you can also add the next CSS to the form: 

.form-sub-label {
font-style: normal;
}
