How will violet appear if more red is used in the red and blue mixture?

Correct answer: Reddish violet

Violet is produced by mixing red and blue. If the proportion of red is increased, red has a stronger visual influence and the mixture shifts toward the red side of the colour range. Thus option B, reddish violet, is correct. Bluish violet would result from using more blue. Yellowish or greenish violet would require introducing colours that are not part of the stated red-and-blue adjustment.
