Step 1: Understanding the Concept:
The principles of design (Balance, Rhythm, Proportion, Emphasis, and Harmony) govern how elements like color, line, texture, and space are combined in an interior.
Step 2: Detailed Explanation:
- Harmony is the design principle that creates a sense of completeness and visual unity by blending similar or complementary elements.
- It is often defined as achieving "unity in variety". This means combining different textures, colors, or shapes (variety) in a way that feels cohesive, ordered, and unified (unity) without becoming monotonous.
- Rhythm through repetition refers to repeating elements to guide the eye smoothly.
- Formal balance refers to symmetrical arrangements of elements.
Step 3: Final Answer
Unity in variety is the defining characteristic of harmony in design.
