Toward which colour will violet shift if blue is greater than red?

Correct answer: Toward blue

The governing concept is dominance in a colour mixture. Violet is made by combining red and blue. If the mixture contains more blue than red, the blue component has greater visual influence, so the violet shifts toward blue. Option B is correct. Yellow would move the mixture away from violet, green comes from blue plus yellow, and orange comes from red plus yellow, so the other options do not fit.
