Difficulty: Moderately Easy
Step1
Choose a single color you'd like to work your decorating scheme around. It can be a traditional color such as red, green, silver or gold or you can use something fun and unexpected like purple, wine or blue. Consider how the color will make the room feel. Warm colors are cozy and comforting, while cool colors make a bold modern statement and call to mind winter elements such as snow and ice.
Step2
Use the darkest shades of your chosen color for the largest objects in the room--for example, on tablecloths and furniture. Dark colors "anchor" a room, making it feel like a cozier space.
Step3
Vary textures used in the room to add visual interest. Combine objects with smooth, shiny surfaces with nubby, highly textured surfaces in the same area. For example, you could use a textured wool or silk tablecloth with polished metal candlesticks on top.
Step4
Choose different finishes of the same color for more contrast. You could use Christmas ornaments that are all the same shade but with matte, glittery or metallic finishes.
Step5
Feel free to go overboard with decor. Monochromatic color schemes allow you more leeway with elements that are typically considered busy, like sparkles, glitter and other reflective surfaces. While these things would make a room decorated in a normal color scheme look cluttered, in a one-color Christmas themed room they fit in nicely.
Step6
Use black and white as needed. Since they're technically not really colors, they can be implemented into monochromatic schemes without detracting from them.
