Day & night shade difference
If you order custom day & night roller shades, you will have 2 separate shades to pull down. Here's a photo of how this RV owner installed her shades in a 2008 Newmar Kountry RV.

Light filtering
The black shade is the screen, used during the day. It let's light through but it offers privacy while you are inside your RV.
Light blocking
The Oyster shade color, in this photo, is the blackout shade. When pulled down, it will block light for nighttime, and sleeping. You can browse more shade color options here.
