Colour in art is a powerful language that conveys meaning, mood, and emotion, arousing emotions and promoting visual harmony throughout history. 

Artists use colour to convey various effects, ranging from cool blues and greens to warm reds and yellows, capturing the viewer's attention and expressing emotions. 

Artists utilize colour in the art to evoke emotions, convey meaning, and influence audience perception, as it differs from the tints and tones perceived by the human eye. 

Primary colours, such as red, yellow, and blue, are the fundamental hues that generate all other colours in traditional art, as they cannot be blended.

Complementary colour dynamics enhance colour intensity, highlight composition details, and generate emotional reactions by contrasting hues against each other, thereby enhancing the overall aesthetic appeal.
