Coloured Lashes from Flutter

I get my lash extensions infilled every three weeks without fail.. it’s my only high-maintenance indulgence but I’m virtually religious about it. For a few months now, I’ve had a few purple ones put in as well that you can only see when they catch the light, which I love because it is a very unexpected look. Now, Kathryn at Flutter http://www.fluttereyes.co.uk/services/faqs-for-eyelashes has found me some that are much finer and just the tips are coloured.. again, they will be used not as the main feature but just with a few here and there. I’m wondering about changing to the blue tipped lashes (my eyes are brown and I wear dark colours on my lids). What do you think?
