How can I change the add to cart button text color on Dawn theme?

I wanted to ask if any one knows how to change the text colour from black to white on the add to cart button on the product page of my shopify site. I am using the dawn theme. Thankyou in advance.

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:
.product-form__submit {
color: white;
}

hi I have added the code but it is not working as shown in image. Am I doing something wrong.

Try this code, but add it to section-main-product.css file

.product__info-container .product-form .product-form__submit {
    background-color: red !important;
    color: white;
}

Try it and let me know
