What result is obtained by adding more red to violet?

Correct answer: Reddish violet

Violet is a secondary colour formed by mixing red and blue. When more red is added, red becomes the dominant component, so the violet shifts toward red and appears reddish violet. Bluish violet would result from adding more blue, not red. Yellowish or greenish violet is not the expected result of increasing the red component. Therefore option B is correct. The governing concept is colour bias: the larger proportion in a mixture influences its visible hue.
