When choosing light wallpapers, you should always remember that they are likely to become yellowish over time.
It doesn't happen with all wallpapers, but it happens to many - and there are a few reasons for that.
Here are a few things that can make your wallpapers yellow.
Sunlight Exposure
Sunlight contains ultraviolet (UV) rays, which have a natural bleaching effect.
When light-colored wallpapers are exposed to direct sunlight over an extended period, the UV rays can lead to a gradual color change.
The wallpaper may begin to fade or develop a yellowish tint, especially in areas where the sun shines the most.
Aging and Oxidation
Over time, the materials in wallpapers can age. They can break down or react with elements in the air, such as oxygen.
This process is called oxidation and can cause the wallpaper to change color, often turning it yellowish.
It's similar to how paper turns yellow as it gets older.
Stains and Smoke
Any particles or substances that settle on the wallpaper's surface can lead to discoloration.
For example, if you have a light wallpaper in a room where smoking occurs, the smoke particles can stick to the wallpaper over time, resulting in a yellowish appearance.
Similarly, cooking residues, dust, or other stains can contribute to the discoloration.
Moisture and Humidity
Wallpaper, especially if it's made from certain materials, can be sensitive to moisture.
In areas with high humidity, the wallpaper may absorb moisture from the air.
This moisture can interact with the wallpaper's materials and cause it to change color, often turning yellow or even developing mold in extreme cases.
What to do?
To prevent or mitigate the yellowing of light wallpapers, you can consider using curtains or blinds to block direct sunlight.
Regular cleaning and dusting can help prevent stains.
Maintaining proper ventilation in your home can also help control humidity and minimize the impact of moisture on your wallpaper.
