Interior Design Principles: Formality and Informality

Study Notes

Interior Design Terminology

Formality in interior design emphasizes dignity, reserve, strength, and impressiveness through elements like unbroken lines, large spaces, and symmetrical shapes and forms arranged at equal distances from the center.
Informality in interior design is expressed through modest size, asymmetrical balance, and broken lines.

Elements of Design

Lines have positive emotional significance and can evoke feelings based on their direction, such as horizontal lines suggesting rest and stability.
Form is the most important element in home planning, and it should suit its function and be influenced by the material from which it is made.
Texture refers to the qualities that are perceptible through the sense of touch and gives character and beauty to objects and interiors.
Pattern refers to surface enrichment and should cover at least 1/4th of the total surface area.

Light and Space

Light is both an art element and a utilitarian element that evokes emotional effects.
A sense of beauty and space leads people to desire large undecorated walls and floors, which is why furniture is often minimal and grouped together.

Color

Color creates depth and is the most powerful tool of a designer, bringing life, beauty, and appeal to a room regardless of cost.
Color can be seen through reflection off a surface or in colored light sources, and contrasting colors can draw attention to specific parts of an image.

Dimensions of Color

Hue is the synonym of color.
Chroma or intensity refers to the brightness or dullness of a color.
Value refers to the lightness or darkness of a color, ranging from white (lightest) to black (darkest).

Types of Colors

Primary colors are basic colors obtained directly from nature, including red, blue, and yellow.
Secondary colors are produced by mixing two primary colors in equal proportion, resulting in orange, green, and violet.
Tertiary colors are produced by mixing a primary color with a secondary color in equal proportion, resulting in six distinct colors.
