If you have a dark skin stick to warm, earthy colors. Gold, bronze and maroon are in fact best for dusky skins. Cooler colors like mauve, pink and silver look better on fairer skins.
Choose lipsticks with matte finish rather than frosted ones. The shades should not be too dark or too light. Medium dull shades would look best. Bright pinks or reds are an absolutely NO! If you have dark lips, before applying lipstick, put some foundation and powder on your lips.
Your blusher too should not be pinkish. Peachish blushers work best on dusky complexion. A gold eyeshadow would be complimentary where as a silver one may not look good.
