The colour, style, pattern of the wallpaper should correspond with the interior for which it is intended. When making a specific choice, be guided by your idea of the final effect you want to achieve through the use of wallpaper. If you plan to spice up the room, for example with a colour accent, opt for a contrasting shade of wallpaper. You can accentuate the overall effect with an interesting pattern. A more subtle way is through related colour schemes that are already used in the interior.
As for the pattern and its size, the smaller the room, the smaller the pattern should be. A larger pattern will not stand out in a small room and will visually make your small space even smaller. For larger rooms, choose from larger patterns and motifs because that is exactly how they will stand out and create the right effect.
We divide colours into warm and cool. Warm colours include yellow, orange, deep orange, red-orange, deep red and their shades. These colours give the impression of warmth, are lively and stimulating, active, dynamic and stimulating. If the room is north facing and colder, warm colours will help to brighten and warm it up. Examples of cool colours are green, blue-green, blue-violet, purple. Their shades give the impression of coolness, soothe and relieve the eyes. They are passive and promote mental concentration.
Too high ceilings are lowered by darker colours in contrast with light walls. The opposite combination, dark walls with a light ceiling, make the space taller but also smaller, the dark walls seem to pull together. So you can make a long narrow room shorter by using a darker colour for the shorter walls, on the contrary, you can make it even narrower by using a dark color on the longer walls.
Stripes on the walls can help you in the same way - if you need to visually enlarge the room, use longitudinal stripes, while vertical stripes are suitable for narrowing the walls.
