When hair is blue, it is recommended that you use __ to balance it.

1. Yellow

2. Red

3. Orange

4. Green

The correct answer is: Yellow

When hair has an intense blue color, using a yellow-based toner or hair product can help balance the shade. The other options, red, orange, and green, would not neutralize the blue tone and may result in a less desirable hair color. Red would likely result in a purple shade, orange could make it more greenish, and green would intensify the blue hue. Yellow is the complementary color to blue, so applying a yellow-based product will help to cancel out the blue and achieve a more natural-looking color.
