(ii) Colour Theory – Colour Theory in design is a set of principles used for working with colors that involves mixing colours, considering the visual effects of color, and creating pleasing color combinations.

(iii) Asymmetrical balance - Asymmetrical balance is a visual shape that looks visually balanced despite a lack of symmetry. Visual balance is most easily achieved with symmetry, a technique that uses mirror-like elements that are the same on opposite sides.
