In decorating, it is important to blend all the elements so they create unity in a certain way. So when you add a new piece of furniture it should belong with the rest of the furniture in the room. This is the goal of harmony and unity.
The Goal of Harmony and Unity
Achieving harmony an unity could be difficult, especially when we believe variety is the spice of life. Since variety is achieved with the use of colour, texture, pattern, mass, and lines (and you should remember contrast do occur within certain elements, but you have to control the degree of these contrast) your ideas must work for you, instead of against you.
Creating Harmony and Unity
With that in mind, here are three things to remember to ensure harmony and unity:
1. You are designing with a purpose in mind.
2. Harmony means to combine the many elements of design in an orderly and pleasing manner, so that one element does not overpower the other.
3. Unity refers to belonging. All elements with the designing scheme should fit together to form that desired picture and mood.
