👉 The term "colouring" refers to the process of using colors or hues to create a visual image, often used in art and design. It involves manipulating the color palette of an object or piece of art to achieve a specific effect, such as increasing contrast between two colors, changing the hue of a shade, or altering the texture of a material. Colouring can be done through various methods, including painting, drawing, printing, and sculpting.
