Colour is essential in art because it acts as a powerful, non-verbal language that evokes emotion, conveys meaning, and directs the viewer's focus. Through colour psychology, artists use warm and cool tones to set moods, create depth, establish narrative, and guide the viewer's eye, often eliciting subconscious psychological reactions.

 Colours directly influence feelings i.e. they have emotional impact. Warm colors can create energy or convey danger, while cool colours often evoke calmness or melancholy.

Colours carry are symbolic and have meaning. They have cultural, historical, or religious significance that helps communicate deeper, often subconscious, messages to the viewer.

By using contrasting colours an artist can to guide the viewer’s eye, making specific, bright, or saturated elements pop against a more muted background.

Ultimately, color is used to translate the artist’s vision, manipulating how a viewer experiences and interprets the artwork.
