Tips for Contouring 1.Choose the Right Shade: Pick a contour shade that is a few shades darker than your skin tone, and opt for a cool undertone for a natural shadow effect. The highlighter should be lighter than your skin tone, ideally with warm or neutral undertones. 2.Use Good Lighting: Natural lighting is best for applying contour makeup so you can see how it looks in different light. Avoid harsh or dim lighting that can distort the appearance of makeup.
