Yellow orange and red orange are examples of which colour group?

Correct answer: Analogous colours

Analogous colours are colours placed close together on the colour wheel. They usually share a common colour quality and tend to blend smoothly, producing a harmonious effect rather than a sharp contrast. Yellow-orange lies between yellow and orange, while red-orange lies between red and orange. Both belong to the warm region and are neighbouring mixtures around orange.

Because yellow-orange and red-orange are near each other on the colour wheel, they form an analogous colour group. Thus option A is correct. Complementary colours stand opposite each other, neutral colours include tones such as grey, white, black, or brown, and monochromatic colour uses variations of one hue rather than nearby hues.
