The importance of colours is beyond the common perception. To keep with its status as one of the leading "visual" arts, painting is heavily dependent upon the use of colour for its impact, mood and depth. While the colours in a painting might be the first thing a viewer notices, there’s a lot more to colour than what meets the eye. The hue, saturation, temperature can change the entire mood of a painting. Colours can be used to harmonize/contrast, unify a scene, produce rhythm or create emphasis. Its effect can be optical, emotional or aesthetic, to only name 3. Research shows that colours can play a major role in our overall state of well-being. The colours we surround ourselves with directly influence the way we feel and relax. Artists learn how to use the positive or negative attributes of colours in their works to subliminally send a message.
