Here's why:
* Unity emphasizes the sense of wholeness and coherence in a design. It's achieved by using elements like repetition, similarity, proximity, and alignment to create a cohesive and harmonious composition.
* Components (like shapes, colors, textures, etc.) are treated as individual parts that, when combined, contribute to the overall feeling of oneness in the final design.
Think of it like a puzzle – individual pieces come together to form a complete picture. Unity ensures that all the elements work together to create a strong, unified design.
