Skin tone and undertone can help narrow lipstick options, but they should not become rigid rules.
How to Choose a Lipstick Shade That Suits You
Natural lip colour, lighting, the rest of your makeup and personal preference can all affect the final appearance.
Use warm, cool and neutral shade guidance as a starting point, compare neighbouring shades, and judge the complete look.
Virtual try-on can also help explore colour options when available, but screen, camera and lighting differences mean it should remain a preview rather than a guarantee.
Ultimately, the most suitable shade is the one that creates the appearance you want and that you enjoy wearing.
