Which mixture will produce red-dominant violet?

Correct answer: More red and less blue

Violet is the secondary colour produced from red and blue. When red is used in a greater proportion than blue, the violet shifts toward red and is described as red-violet, making option B correct. More blue would create blue-violet. Yellow is not a component of violet in this traditional model, and equal yellow and blue produces green rather than violet. The dominant component determines the visible colour bias.
