It is important to know the emotions and meanings that colours represent, particulary when choosing colours for a brand or advertising. This will represent you and your company and you do not want to alienate your target audience. Beware of fashions and trends as these have a limited lifespan.
Harmony is something that is pleasing to the eye. It engages the viewer and it creates an inner sense of order, a balance in the visual experience. When something is not harmonious, it’s either boring or chaotic. At one extreme is a visual experience that is so bland that the viewer is not engaged. The human brain will reject understimulating information.
At the other extreme is a visual experience that is so overdone, so chaotic that the viewer can’t stand to look at it. The human brain rejects what it can not organize, what it can not understand. The visual task requires that we present a logical structure. Colour harmony delivers visual interest and a sense of order.
