Hi James-
Thanks a lot for the clarification, I see what you mean now that the Label for the variations was the light color.
Here’s a Custom CSS rule you can use in your Customize > Advanced > Custom JS & CSS menu:
.woocommerce div.product form.cart .variations label {
color: #333;
}
The color #333 is based on the text in the paragraph just above the selection box, but you can change that according to your taste. Once you have that CSS rule in place, you can change your background color back to white.
