My bad! @schikinoils : Please accept my apologies. And, please use this code and paste this in your (base.css). That’s the only code you need to add.
.product-form__input--pill input[type=radio]:checked+label {
background-color: #7F5777 !important;
}
Feel free to reach out in case you’ve any more questions
Also, it’d be great if you can like and mark the solution as accepted.
Cheers!
