It is difficult to really define what is the human backdrop. The guys are a diverse group with a wide range of practices and attributes. To label an entire genus with a certain personality is a dangerous habit.
However, there are certain things in our society that are stylistically masculine. Not a firm scientific decoration, they are more a philosophy, a set of intrinsic notions that give us a common artistic playground to work on. Some things just look girly, and some things seem masculine. It's as obvious as the difference between pink and blue.
Defining male decorating preferences is really a question of understanding the psychology we expect from this genre. The male decor is, by its very definition, not a feminine setting, and therefore its essence will be made up of the difference between the spirits of the two.
One of the things that society thinks of men is that they are more functional than women. While women appreciate beauty, guys like things that work. In fact, common concepts claim that men are actually annoyed by unnecessary decorative touches.
This means that one of the key elements of decorating dudes would be to choose the function rather than the form. A delicate coffee table made of stainless steel sliding strips will be lost on a solid oak worktable.
Another manifestation of this trait is the male tendency to decorate using their hobbies and interests. Sports accessories, toys, models, these are the favorite accessories of a manly play. Meanwhile, flowers and incense sticks, candles and laces, objects that create an atmosphere and nothing else, are generally considered more feminine in their nature.
Another aspect of male decor is that men are generally taller than women. This means that they need more space to be comfortable. They must be able to stretch and feel that the world around them is proportional to their size.
One of the most stereotypical pieces of guy decor is the reclining chair. Often, it is the only piece of furniture that is large enough to fit comfortably into a man's body. Capable of leaning back and stretching, they can usually support the majority of the size of a tall man, in a comfortable and relaxing way.
Size and function tendencies collide in other aspects of the decoration of dude. Men tend to like big dressers, big beds, big shelves and big drawers. It's both because the imposing size fits them, and because these objects tend to do their job better. Larger containers hold more. Larger beds comfort more. The larger dressers are usually stronger and more durable.
Men also tend to like the different colors of women. Guys tend to be attracted to darker, more down-to-earth colors. Red, brown, black and green are traditionally masculine and, in some shades, have a distinct masculine feel.
Although these trends may be true for some men, every guy is different. What is important when creating a space is that you take the desires and preferences of all those who inhabit it, men and women, and find out where your tastes overlap. Compromise in decoration is the art of creating a symphony from many different visions.
