Follow these steps:

Hello There,

1. In your Shopify Admin go to online store > themes > actions > edit code

2. Find Asset > base.css and paste this at the bottom of the file:

.quick-add .quick-add__submit {
background-color: #000;
color: #fff;
}

Thank you. I want to change color too, but also height of the buttons and make them round. Is there a way to add these simple settings straight into the "theme settings"?
