Can I change the colors of the Stars and submit button in Vintage Star theme?

Also, can I change the colors on the stars in the heading and the background color of the button? See screen shot.  

This is a test site that I am working on.

Inject the following custom CSS codes to change the color of the stars:

.form-header:before, .form-header:after {

    color: #2e7be3 !important;

}

You will have to change #2e7be3 to your preferred color. Color hex codes here https://www.w3schools.com/colors/colors_picker.asp. 

As for the background color of the submit button, inject the following custom CSS codes:

.form-all .qq-upload-button, .form-all .form-submit-button, .form-all .form-submit-reset, .form-all .form-submit-print {

     background: #2e7be3;

}

Again, just change the color your preferred one.
