Apple Watch Series 6 Product Red Bands

Hello

I want to buy a 44mm apple watch series 6 product red (aluminum) , but when I go to the watch studio and select the 44mm aluminum red case I cant select a watch band that is not a product red band, I can only select red product bands.

Can I use other bands that are not product red in the Product red apple watch?

Can I use a product red apple watch (44mm) with a Milanese band?

Thank you!
