When hair is violet, it means it has a lot of blue and red tones mixed together. In order to create a balanced and natural looking color, it's recommended to add in some yellow tones to counteract the blue and red. Choosing any of the other colors, such as blue, green, or red, would only intensify the existing tones and potentially make the hair look unnatural. Yellow is the complementary color to violet, which is why it works to balance out the color.
