From the very first moment when a child starts to explore their environment, colours for them become very attractive and interesting. In this context, colours become more than visual stimuli; they eventually become a language that helps a child to communicate, express their feelings and develop their imagination. Through play, drawing and day to day interactions, children gradually become more familiar with various colours, they learn their names, create connections between colours and reality. Expressing emotions is a key component to a child's emotional development. In the early stages of life, children are faced with a wide spectre of emotions that are difficult for them to express verbaly. In these moments, art, such as a drawing, plays a vital role by giving children the opportunity to express their emotions in a different and easier way for them. Through artistic expression, children find a safe space to explore and express their emotions. This paper examines the psychological properties of colours and their influence on a child. It analyzes how music can affect artistic expression in children and it explores ways in which a child can express their emotions.
