Ericachristina has some excellent suggestions. The foundation samples in Sephora are completely free.

Some makeup lines that have a lot of different foundation colors are Clinique, Estee Lauder and Lancome. These are available at dept. stores (and Lancome and Clinique is available at Sephora). These makeup lines will let you have free samples so you can try them at home and with different lighting. Nars and Mac also have a good range of light colors which is what your skin tone would probably use.

Have fun experimenting!
2/c and some 3A.
Protein sensitive but can use occasionally
Highly porous. Color over grey.
Best 1st day method: Super Soaker
Stylers: Mix Curls in a Bottle into everything for shine. Terrible pj
Sometimes try roller sets - classic glamor but I prefer my curls.
Every day is a gift
