Can I change the add to cart button color for a product block in Moksha?

I am using the Moksha template and want to make the add to cart button a different color. When i try in style editor it also changes the submit button on the contact us email block. i used this css but it did not work.

.product-block .buy-button, .product-block .sqs-add-to-cart-button { font-size: 18px; background-color: #ff9900; padding: 1em 1em !important; }

is the code wrong or is it just not possible?

my website is www.christaylormft.com

the page I'm trying to change is www.christaylormft.com/back-to-basics-sales-page

@ctaylor281 You mean Buy Now button? Add to Home > Design > Custom CSS

.sqs-add-to-cart-button {
   background: #f1f2f3 !important;
   border-color: #ff0000 !important;
   padding: 20px 50px !important;
   font-size: 30px !important;
}
