Interior Decorators and Interior Designers

Interior design is the art and science of understanding people's behavior to create functional spaces within a building. Decoration is the furnishing or adorning of a space with decorative elements, sometimes complemented by advice and practical assistance. In short, interior designers may decorate, but decorators do not design.

Interior designer implies that there is more of an emphasis on planning, functional design and the effective use of space, as compared to interior decorating. An interior designer in fineline design can undertake projects that include arranging the basic layout of spaces within a building as well as projects that require an understanding of technical issues such as window and door positioning, acoustics, and lighting. Although an interior designer may create the layout of a space, they may not alter load-bearing walls without having their designs stamped for approval by a structural engineer. Interior designers often work directly with architects, engineers and contractors.

Interior designers must be highly skilled in order to create interior environments that are functional, safe, and adhere to building codes, regulations and ADA requirements. They go beyond the selection of color palettes and furnishings and apply their knowledge to the development of construction documents, occupancy loads, healthcare regulations and sustainable design principles, as well as the management and coordination of professional services including mechanical, electrical, plumbing, and life safety—all to ensure that people can live, learn or work in an innocuous environment that is also aesthetically pleasing.

Someone may wish to specialize and develop technical knowledge specific to one area or type of interior design, such as residential design, commercial design, hospitality design, healthcare design, universal design, exhibition design, furniture design, and spatial branding. Interior design is a creative profession that is relatively new, constantly evolving, and often confusing to the public. It is not an artistic pursuit and relies on research from many fields to provide a well-trained understanding of how people are influenced by their environments. 

Color is a powerful design tool in decoration, as well as in interior design, which is the art of composing and coordinating colors together to create a stylish scheme on the interior architecture of the space.

It is essential to interior designers to acquire a deep experience with colors, understand their psychological effects, and understand the meaning of each color in different locations and situations in order to create suitable combinations for each place.

Combining colors together could result in creating a state of mind as seen by the observer, and could eventually result in positive or negative effects on them. Colors make the room feel either more calm, cheerful, comfortable, stressful, or dramatic. Color combination make a tiny room seem larger or smaller. So it is the Interior designer profession to choose appropriate colors for a place in a way people want to look and feel in the space.
