Which quality becomes stronger by using similar colours and shapes more?

Correct answer: Unity

Direct answer: C, unity. In a composition, unity means that the different parts look related and belong together. When an artist repeats or uses similar colours and shapes, the viewer notices a connection among those parts. For example, several blue shapes or repeated circular forms can make a picture feel organised and harmonious. Contrast has the opposite purpose: it creates noticeable differences. Disorder means a lack of organised relationship, and roughness describes a surface quality rather than the relationship among colours and shapes. Therefore, similarity strengthens unity. A is incorrect because contrast depends on difference, not similarity. B is incorrect because repeated similarities usually reduce confusion rather than create disorder. C is correct because repetition and similarity join parts into one visual whole. D is incorrect because roughness concerns texture. Memory cue: “similar parts stay together”—similarity and repetition support unity.
