There are a huge number of people on the planet, the same number of characters, opinions, and interests on the planet - we all differ not only in our interests and tastes, but also in our preferences. Basically, all psychotypes have already been studied; psychologists in this regard divide people into special classifications. Hippocrates had the following opinion, dividing people into the following classifications: energetic choleric people with a hot temper, cheerful and cheerful sanguine people, sad and irritable melancholic people, calm and indifferent phlegmatic people. These classifications work everywhere you can imagine that a person faces: on study, in the work team, in the family circle. Of course, their character traits can be seen in the interiors they choose for themselves. Interior design (French in-térieur, Latin in-terior - internal view) is based on a synthesis of pragmatic and artistic ideas and solutions aimed at improving the human condition in a holistic, aesthetically perfect form. According to experts, sanguine people have the greatest preference for spacious houses and apartments with the least amount of furniture and all kinds of fittings and the maximum amount of free space. To visually increase space, sanguine people prefer huge mirrors on the walls, light colors on painted walls, and bright light. They do not recognize any particular style; they create their interior in accordance with their own characters, tastes and needs. Cholerics, with their lively, restless and explosive character, constantly improve their home, each time bringing a new zest to it. The interior should be calming, green tones are most suitable for this purpose, turquoise and blue look good, khaki is no less magnificent. They also include a country-style interior among their preferences. Cholerics prefer simple elements, calm tones. A melancholic person should feel calm and protected in his home. Their home is an impregnable fortress; there should be a corner in it where he could remain alone with himself. As for colors, pastel colors are most preferable here: light brown, a little beige, soft pink. Bright colors, on the contrary, are strictly contraindicated. With the exception of the place where the melancholic works. Bright colors will be preferable in this zone. The most famous styles include Baroque and Biedermeier. A phlegmatic person needs confidence, reliability in everything, even the design of his own home should not raise any doubts. The phlegmatic person gives the greatest preference to taste to durable, reliable furniture, calm shades of bluish-gray, brown, light green shades. It is best to decorate the work area more brightly, using ethnic decorative elements. The most important place in the world for everyone is their home. As the English proverb says, There's No Place Like Home - there is no place like home. We love returning to our home; we feel comfortable and safe there..
