The colours in the interiors should be used in moderation, remembering that what looks intriguingly at first glance may turn out to be tiring after a few hours. The safest and most popular colour is white and its shades. It creates the illusion of a larger space, which is why it is perfect for small rooms and flats. Yellow adds energy and stimulates life, just like orange and red. Pink is associated with eroticism, it is the colour of people who like sensual sensations. In turn blue, the colour of water and sky, is cool and soothing, similarly to green, the colour of hope, spring and nature. Purple is mystical and mysterious, yet gentle. Brown, the earthy colour, is safe and warm. Black color is identified with mystery, it inspires, but in excess it gives an overwhelming effect.
Colours can be divided into several groups. Thus, the colours of the earth refer to the natural colours occurring in nature (the colour of sand, rocks, earth, plants). They look nice in combination with wicker or real wood furniture and plants. These colours are neutral, so they can be combined with each other and with other colours at will. Pastel colours are very calm, bright, with a big admixture of white. They can be used in all rooms and can be combined with other colours, especially clean ones. Cold colours (blue, turquoise, navy blue, grey) give the impression of coolness and distance. They are associated with water and sky. They are recommended for hot, tight and dark places, because they cool down, enlarge and brighten the room optically. They are ideal for warm climates and for rooms facing south or west. They are conducive to mental work. Warm colours (red, yellow, orange) seem to come closer to the viewer. They are recommended for large and cold rooms, oriented towards the north or east. They are perfect for cold, rainy climates.
Optical illusions can deceive our eyes and brains, but our bodies are three-dimensional. If there is too much furniture in a small room, we will come across it. Furniture should be moved a little away from the walls. When revealing the floor, we pull our attention away from the corners, and the room seems bigger. Space is important for the body – this is where the rules apply. We like to look at people from a distance. We have our own personal space – we make sure that others are not too close. The distance varies from culture to culture, but is on average about one metre. From this distance we can look into the eyes of the interlocutor and read the body language without moving our eyes. When we are too far away, we do not see the facial expression of the interlocutor. When it is too close, we have to move our eyes from the eyes to the mouth. It is worth remembering this when arranging the room where we will receive guests.
