What range of products & colours do you think suits dark people in terms of make-ups? Sometimes I come across some rily dark chicks that use compact powders and it seems like they have pop or nixoderm on their faces (Horrible) with some very funny colours as lipsticks, eyeshadows etc making them look like clowns. What particular colours do you think suits dark skin??

you can really wear any color eyeshadow.
its just depends on the application,

have u tried iman ?

You can try black radiance products. They are made specifically for black women.
As for colour, grey eye shadow is the best colour for dark women. Golden is also ok.Just make sure it is used minimally. Remember it is called eye shadow not eye colour.
As for lip stick I think dark colours are the best. Avoid colours like pink, grey, blue, gold etc.
