If you put orange over blue hair, the resulting color will depend on the shade of blue and the level of saturation of both colors. Generally, when you mix complementary colors like blue and orange, they can neutralize or cancel each other out.
If the blue hair is a lighter shade, the orange can result in a brassy or coppery tone. This is because orange has warm, red undertones, and when mixed with blue, it can create a reddish-brown color. If the blue hair is a darker shade, the orange may not be as noticeable, but it can still create a subtle warmth to the hair.
It is important to note that putting orange over blue hair can be a risky move and can result in unpredictable outcomes. The final result can depend on the type of dye used, the condition of the hair, and how long the dye is left on the hair. Additionally, if the blue hair was previously dyed, the orange dye may not be able to penetrate the hair shaft properly, resulting in an uneven color.
To avoid a potentially disastrous outcome, it is recommended to consult with a professional hairstylist before attempting to color your hair at home. They can help determine the best course of action based on the current condition and color of your hair and provide recommendations for achieving the desired result.
In some cases, if the blue hair is already faded or washed out, it may be necessary to remove the blue dye completely before attempting to add orange. This can be done through a process called color correction, which involves using a hair color remover to strip the hair of its current color and then reapplying the desired color.
In summary, if you put orange over blue hair, the resulting color can vary depending on the shade of blue and the level of saturation of both colors. While it is possible to create a unique and interesting look, it is important to proceed with caution and seek professional advice if you are unsure about how to achieve the desired result.
