Moodboards give an impression of what is envisioned for a space through a collage of images. This could be images of inspiring rooms, specific products or other elements that add to the concept.
Moodboards are also used to evoke a feeling about the concept. The purpose of interior design is threefold, namely the functional improvement, aesthetic enrichment, and psychological enhancement of the quality of life in interior spaces. So, besides the functional and aesthetic side, a moodboard can also be used to appeal to a psychological response. A colour can evoke a certain feeling, or you can have an immediate response that you either love or hate a style or object shown on the moodboard.
