Hello! As any skin color in my opinion, the more color you want on your eyes, then you should go for the "darker" colors. But if you want a more natural look, stick to a color that looks similar to your skin tone.
As for lips, I would recommend not using concealer as the main lip color because most of the time it makes you look "washed-up", maybe use the concealer to mute the original color of your lips and add a bit of color to the lips (peach, pink) to make it a little more colorful (still nude).
Hope this helps
