* Pink: Pink is a common color that emerges as a base. pH-reactive lipsticks often shift towards a rosy or berry pink as they interact with the skin's acidity.
* Red: Red is the original color. Red is commonly emphasized when a lipstick changes color.
* Mauve/Berry: Depending on the initial color and the individual's skin chemistry, the color may shift towards mauve or berry tones, which are a blend of pink, purple, and red.
* Purple: On individuals with basic (higher pH) skin, the lipstick may emphasize the purple color.
* Warmer or Cooler Undertones: Color-changing lipsticks may also bring out the underlying warm or cool undertones in the lips.
