Hair color formulation takes into account the underlying pigments present in the hair, which significantly influences the final result of the coloring process. When coloring hair, the natural pigment—melanin—underneath the hair's outer cuticle layer plays a crucial role.

For example, when lighter shades are applied to dark hair, the existing pigments can affect how the final color appears. If the natural hair tone is warm (such as red or orange), these underlying tones can mix with the new color, altering the final result. Therefore, understanding the natural hair tone and its underlying pigments allows the stylist to predict how the chosen color will react and guide adjustments to obtain the desired shade.

The other choices do not accurately reflect the relationship between hair color formulation and underlying pigments. Ignoring underlying pigments or assuming they have no impact can lead to unexpected colors, and while canceling out undesired tones can be a part of the process, it does not encompass how underlying pigments need to be accounted for in an overall formulation strategy.
