Which color is an example of a neutral tone?

Tan is considered a neutral tone because it combines warm and cool elements, creating a balanced hue that can complement various skin tones and colors. Neutral tones typically don't lean significantly towards cool or warm color families, making them versatile in application, especially in hair coloring. They serve as a great base or background for other colors to be layered on top and are often used to create subtle highlights or lowlights that enhance overall dimension without overwhelming the natural hair color.

In contrast, colors like yellow, blue, and green are classified as more distinct tones that belong to specific color families. Yellow is warm, blue is cool, and green can vary depending on the balance of warm or cool undertones present, but none of them provide the neutrality or wide applicability that tan does. Therefore, tan is the ideal example of a neutral tone in this context.
