Interior design is "the art or
process of designing the interior
decoration of a room or building“
An interior designer is someone
who coordinates and manages such

profession that includes conceptual
development, communicating with the
stakeholders of a project and the
managementand execution of the design.
In the past, interiors were put together
instinctively as a part of the process of

These pieces work together to form
a unified composition, and when
utilized successfully, create a strong,
dynamic visual layout.
The designer uses these elements
as tools that control how a message
is delivered to an audience.
These principles can be applied to
fine art, photography and graphic
One of most important element of design, line defines a subjectʼs form or shape on a flat, two-
Lines can be thick or thin, smooth or jagged, rigid and mechanical or organic and hand drawn.
When discussing line as it applies to interior design, we mean the lines created by the furnishings
and architecture of a room.
Line sets form and shape.
Line is responsible for harmony, contrast and unity in interior design.
Line can be used to show movement and guides the eye throughout a room.
Line can be used to show mood.
Lines can be used to convey a sense of strength, serenity, gracefulness, or action.
Combining lines and placing them in a design in certain ways can create specific effects and feelings.
The use of line can also have an effect on how space is perceived.
Different types of lines have different effects on design.
a mark, or stroke that is longer then it is wide. It is the path of a point moving
in space. Objects and things are perceived by the line that describes them.
Characteristics of line include:
Width - thick, thin, tapering, uneven
Length - long, short, continuous, broken
Direction - horizontal, vertical, diagonal, curving, perpendicular, oblique,
parallel, radial, zig-zag
Focus - sharp, blurry, fuzzy, choppy
Feeling - sharp, jagged, graceful, smooth ... can you think of others?
Vertical lines lead the eye up,
strength to a design.

Space, in two-dimensional design, is essentially flat.
It has height and width, but no depth.
There are certain visual cues, however, that can create the illusion of space in
the mind of the viewer.
By using those cues, artists and designers can create images that are interpreted
Space is the area provided for a particular purpose.
It may have two dimensions (length and width) such as a floor, or it may have three
dimensions (length, width, and height), such as a room or dwelling.
It refers to the area that a shape or form occupies.
When space changes gradually, it is more pleasing than when it changes abruptly.
When space changes suddenly, the eye shifts from one view to the other without
making a smooth transition.
Space can be defined
as positive or negative.
Positive space is the filled
space, the object(s) or
element(s) in the design.
Negative space is the empty
space, or the open space
between design elements or
objects, such as a

•Linear perspective in a photorealistic image.
Linear perspective is
based on the visual
phenomenon that as
parallel lines (such as
railroad tracks) recede
into space, they appear to
converge at a distant
point. Linear perspective
not only evokes a feeling
of great depth, but it also
creates a strong focal
point at the place where
the lines converge.
Size is one of the
easiest ways to
create the illusion of
space. A larger
image will appear
closer than a smaller
one because we
observed (very early
in life) that objects
appear to become
smaller as they get
Overlapping is another easy way to suggest depth in
an image. When objects overlap each other, the
viewer perceives the one that is covering parts of
other to be in front and the one that is covered to be
in the back.
Atmospheric perspective uses value,
contrast and color to give the illusion
Atmospheric perspective is based on
the fact that the farther something is
away from us, the more the
atmospheric haze may obscure our
view of it.
By lightening the value, lowering the
value contrast, softening the edges,
decreasing detail and muting the
color, you can mimic the effect of
atmospheric haze and create the
illusion of increasing distance.
Increasing the bluish cast of an image
also creates a sense of depth because
cool colors recede and warm colors
Compositional location refers to where a form is
positioned vertically in the image. The bottom is
seen as the foreground, the part of the image that
is nearest the viewer and the top as the
background, the part farthest from the viewer. The
higher an object is place in the image, the farther
back it is perceived to be.
Very large rooms designed for many people can produce a
lonely feeling when a person is alone
Space is affected by the
number and size of
objects in it.
Many objects scattered
throughout a room will
most likely destroy the
design effect because the
space will have no
Objects grouped into
large unitswill create a
more ordered space.
A shape is defined as
a two or more dimensional area.
All objects are composed of shapes and all other
'Elements of Design' are shapes in some way.
Shape is a flat image with two dimensions: Length and
Any self-contained area with defined form or outline.
It refers to the nature of an enclosure, actual or implied,
formed by a line/curve on a flat surface.
Examples of "shape" in this context include "a geometric
shape" (eg square), "organic shape" (flower-shaped object).
Shapes can be created by enclosing line, or by color and
value changes which define edges.
Mechanical Shapes or Geometric Shapes
are the shapes that can be drawn using a
ruler or compass. Mechanical shapes,
whether simple or complex, produce a
feeling of control or order.
Organic Shapes are freehand drawn
shapes that are complex and normally
found in nature. Organic shapes produce a

Shape may be:
Form is the outlined edges of a three-dimensional
It has length, width, and depth (or height) as well
as volume and mass.
Form can be measured, from top to bottom
(height), side to side (width), and from back to
Form is also defined by light and dark.
It can be defined by the presence of shadows on
surfaces or faces of an object.
There are two types of form, geometric (man-
made) and natural (organic form).
Form maybe created by the combining of two or
It maybe enhanced by tone, texture and color.
It can be illustrated or constructed.
It has volume and mass.
Organic - natural, living form.
Inorganicor geometric - man-made, non-living
Open-forms - forms that can be looked into.
Closed-forms - self-contained.
GeometricShape - circle, square, rectangle, triangle,
pentagon, octagon, other polygons.
GeometricForm - sphere, cube, pyramid, cone,
Free-Form - any non-geometric shape: irregular,
Inorganic or geometric - man-made, non-livingforms.
It is the surface quality or appearance of an object.
Texture can be used to enhance a room’s features or
provide added dimension.
The element of texture is defined as “the feel,
appearance, or consistency of a surface.”
Texture is a surface’s tactile quality.
Tactile refers to the perception of touch.
Visual texture is a quality of the surface that you can ‘see’,
but not necessarily ‘felt’.
Actual texture is a qualityof the surface that you can both
‘see’ and ‘feel’.
Texture may be :
A room with the same texture throughout is monotonous,but
too many different textures can appeardisjointedand
Most well-designed rooms have a dominatetexture with
accents of contrastingtextures.
Often patternsor colorsare used to create the illusionof
Smooth surfaces reflect more light than rough surfaces, making
them look lighter and brighter.
Rough surfaces absorb more light, making them look darker
and less intense.
Color is the key element of interior design.
It is used to create aesthetically pleasing combinations and
also works on a psychological level.
Each color has three characteristics: hue, value, and
It can give emphasis to create a hierarchy and the piece of
Colour Saturation gives a color brightness or dullness.
Colour mayconnote emotion (excitement, rage, peace)
and stimulatebrain activity (action, relaxation,
Light is additive – working towards white.
Paint or pigment is subtractive – working towards black.
Mixing red blue and yellow can create any pigmentcolour.
Tints are made when white is added to a pure hue to make
A Shade is when black is added to a pure hue to make
Hue is the name of a color.
Red, green and blue-violetare examples of hues.
A color may be lightenedor darkened, brightened or dulled,
but the hue will remain the same.
Colouris said to have value,which refers to the lightnessor
darkness of the colour(hue).
Tint (colour pluswhite) is high-valuecolour, whereas shade
(colour plusblack) is low value colour
Primary colors are hues from which all other colors
can be made: red, yellow, blue.
Secondary colors are made from mixing equal
parts of the Primary colors: orange, green, violet.
Tertiary colors are those colors between Primary and
Secondary colors: yellow-orange, red-orange, etc.
Complementary colors are colors that are opposite
each other on the color wheel: red-green, orange-
Analogous colors are colors that are adjacent (side by
side) to each other on the color wheel.
Monochromaticcolors are variations in value of one
color by adding either white to make tints or black to
refers to the brightness or dullness of a color.
Intensity is the brightness or dullness of a hue.
Adding some of its compliment can lower the
intensity of a hue. The compliment of a hue is the
color directly opposite it on a standard color wheel.
Examples of high intensity colors include hot pink and
fire-engine red. Low intensity colors include rust and
A color is Transparent if the viewer can see
clearly through it.
A color is translucent if it admits light but the
image is diffused and can not be seen clearly.
A color is opaque if it can't be seen through.
Colors have degrees of transparency
Descriptors: brilliant,medium, dull.
Value is the lightness or
darkness of a hue.
The value of a hue can be
made lighter by adding white.
This produces a tint.
Pink is a tint of red, made by
adding white to red.
A hue can be made darker by
adding black. This produces a
Maroon is a shade of red.
Google knows how to apply colour in a way that not only
enforces their brand, but also to create a fun and interesting
working environment that benefits their employees.
The Red Prime Steak restaurant takes advantage of colour
psychology by using the colour red to increase appetites.
The offices of Octavian Advisors utilizes a monochromatic
colour scheme, except for the bright green elevator
entrances. This is an effective way of using colour for way

Colour can be applied to surfaces or as light to create
interested and dynamic spaces.
