Unity

Grid 

• Divides an area to create a certain framework of ideas
• Example: The outdoor area

Gestalt

• Theory of visual psychology
• This bookcase looks like a simple bookcase but it serves as a hidden door as well

Visual Perception 

• Organization to relate to various elements
• This staircase is simple and white like it's surroundings

Ways to achieve unity

 Continuation

• A certain element that continues
• The green repeats in this bedroom 

 Proximity 

• To make separate items look as if they belong together 

Repetition

• Pattern that makes things relate to each other
• All the tan items seem as if they match although they are all different

 Variety

• Although nothing matches it still looks appealing because there are accents of every color everywhere

 

 

Varied Repetition

• The colors are repeated but there is a variety with the pink accents 
• Adds visual interest by showing some variation
