Laura Mercier Tinted Moisturiser Shades

[plotmissinginaction]

I would like to try this but I live in the arse end of nowhere and so I would need to order it online. However I have absolutely no idea what shade I should go for. Any clever ideas for working out what might be best?

I do this as I also live in the arse end of nowhere (maybe we're neighbours ) I tend to read blog reviews as they usually give a fairly detailed breakdown of the shade, tone etc. To be honest it's easier with me because I just have to choose the lightest one but I like to make sure it's not going to be too yellow so that's why I look on blog reviews.
