There are many types of mood boards: material swatches, color palettes, finishes, experience and mood, overall appearance, etc.There is no right or wrong way of putting together one either, because it all comes down to the architect and what you are trying to convey, so make sure to be as explorative as possible.
Mood boards are put together to communicate design concepts easily with people who were not involved in the design process.
Design projects rely heavily on visual tools that illustrate the project's features and overall atmosphere, and whether you are an architect, interior designer, furniture designer, or engineer, the term 'mood board' has definitely come up at some point during the early stages of the design process.
