I know it might seem obvious but I tend to like some colour to my face yet I am conscious that when I buy a darker foundation I have tide marks, even with a darker colour tinted moisturiser.
I did once have the No7 foundation match thing done and was matched as 'cool ivory', I have never used an ivory foundation before. I had a sample and it did look natural but then I just bought the darker shade anyway.
Also I don't like to bother buying different foundation shades for different times of year so what if the match made one is too pale in summer when I get a bit of colour?
What do you do?
