Back button fatigue
Let's say I have two pages, a list of products "Product List" and the "Product Page" itself.
When I click on a product (e.g. a phone) I'd like to explore its variations (e.g. colour variation).
Case A: Each colour variation opens a new page. I've checked 8 colours. I'd like to go back to the "Product List". I have to press the back arrow on my browser 8 times.
Case B: Each colour variation doesn't open a new page. I've checked 8 colours. I'd like to go back to the "Product List". I press back once.
Which of these cases are users more accustomed to?
