My boys are 2 years apart and as soon as my youngest was out of the crib I wanted my boys to share a room! After having toddler beds for a few years, it was time to upgrade to twin beds. I immediately knew I wanted a black metal bed for my boys and a pop of color! That was my starting point. I also wanted to use as much from both of their nurseries as possible because I still loved the woodland/mountain/outdoor theme but wanted to add a NEW color to change it up a bit! I found a vintage washed green quilt from the target pillowfort collection and knew that was the color I wanted to use. My advice would be find the items you really love that make the room unique but don't feel like you have to buy everything brand new to create an entirely different look! I try to buy decor items that can grow with my kids and can be used for a long time. For an example, when I got their toddler bed comforters I already had in mind that I would use them across the end of a twin bed one day! Take a look at Beckett's Adventure Nursery and Bowen's Woodland Nursery to see all of the items I incorporated from their nurseries into their big boy room!
