Hi Nikki,
I would always try to use foundation that matches your skin colour and tone. Test this on the jaw line area to get a true colour match. You can then add life to the skin with a blusher and bronzer.
Blusher on the 'apples' of the cheeks, i.e. the round area that is prominent when you smile, and then a light dusting of bronzer over the cheek bones, forehead and down the bridge of your nose - these are all areas that the sun naturally bounces off!
