Color tones can vary due to your laptop (computer) brand and/or monitor settings. For example, on Macbook you will see color more yellow compared to HP, were it will definitely appear more cold and blue. Please, understand that we can do nothing with that. We are trying to take the best pictures and show you, how exactly the item will look. The color on the pictures are for reference only and may slightly differ from the actual color on a roll. All pictures represent an actual item. We understand, that it is hard to buy wallpaper online, that's why we are selling, so you can order them, and see the actual print, color, and quality. Thanks for understanding. You will need to buy an adhesive in order to hang those wallpaper. Please, calculate your room size carefully to make sure it is enough for your fitment.
