Interior design is the art and science of understanding people's behavior to create functional spaces, that are aesthetically pleasing, 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===
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 fine line 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]].<ref name="autogenerated2003"/> 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 [[Americans with Disabilities Act of 1990|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 always an artistic pursuit and can rely on research from many fields to provide a well-trained understanding of how people are often influenced by their environments.

=== Color in interior design ===
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.<ref>{{Cite news|url=http://www.interiordezine.com/color/|title=Color Wheel, Color Schemes, Color Therapy, Colors by Interiordezine |newspaper=Interiordezine.com| access-date = 2016-10-19}}</ref><ref>{{Cite web |last=Devin |date=2024-08-16 |title=Interior Color Schemes for Houses: Add Color, Avoid Clashes |url=https://georgesolution.com/interior-color-schemes-for-houses-add-color-avoid-clashes/ |access-date=2025-05-22 |website=George Solution |language=en-US}}</ref>

It can be important to interior designers to acquire a deep experience with colors, understand [[Color psychology|their psychological effects]], and understand the [[Color symbolism|meaning of each color in different locations and situations]] in order to create suitable combinations for each place.<ref name=":1">{{Cite web|url=http://designlike.com/the-psychology-of-color-for-interior-design/|title=The Psychology of Color for Interior Design – Interior Design, Design News and Architecture Trends|website=designlike.com|date=5 October 2011 |access-date=2016-10-19}}</ref> Color is something that an interior design needs to understand. Color can affect the way that humans think, feel, or look at space. Color can have a major effect on human behavior through all ages. An interior designer must understand that different colors can easily overstimulate people depending on the environment. Color can also have effects on a room. For example, if someone is claustrophobic then painting a room in darker colors could make the room feel smaller therefore the person could feel trapped.

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 can make the room feel either more calm, cheerful, comfortable, stressful, or dramatic. Color combinations can make a tiny room seem larger or smaller.<ref>{{Cite news|url=http://www.hgtv.com/remodel/interior-remodel/the-psychology-of-color|title=The Psychology of Color|newspaper=HGTV| access-date=2016-10-19}}</ref> So it is for the Interior designer to choose appropriate colors for a place towards achieving how clients would want to look at, and feel in, that space.<ref name=":1"/>

In 2024, [[Red|red-colored]] [[home accessories]] were popularized on social media and in several design magazines for claiming to enhance interior design. This was coined the [[Unexpected Red Theory]].
