Hey Danielle and Genevieve - The curving trellis design is what the paint would go through. Stencils are great because you can use any background and stencil colors you want. Wallpaper comes in limited color options and is hard to pair with your already existing decor. Wallpaper also damages your walls and is expensive, whereas stenciled designs can just be painted over and are pretty budget friendly!

What pant color is used I'm this design, both of them if possible

Hello Maria, We're not sure what paint colors are used here, but the gray-purple colors sure do look beautiful!
