I really wish I had a natural flair for putting colours together. It seems I'm always getting one element of my make up wrong. Whether it's a clashing lipstick or a poor choice of blush, it certainly seems to be a common occurrence. I read about how to pair colours and how to work out what undertone you are but I'm still prone to mistakes.
I have got a lot better at choosing things that suit my colouring. Through a process of trial and (a lot) of error I know that I can wear ashy tones but that warm, red based shades are a total no, no! I've tried a lot of eyeshadows for blue eyes which promised to make my eyes pop but I can assure you just made me look ill. Some memorable errors were Woodwinked, Cranberry and Rubenesque paint pot (from my MAC only era). All lovely colours just no good on me. I don't seem to make as many errors with lipstick but it has happened. Angel was the biggest disappointment. This is so popular and I really like the colour but on my lips? A definite fail!
So, now even though I have purged my collection of the colours that don't suit me I still manage to mess it up by choosing lipstick, blush and eyeshadows that don't compliment each other. I can see the mistakes once it's on my face though. I recently read a post by Confessions of a Makeupholic about how to match your blush with your eyeshadow, I still haven't quite got it though so I think more research is required. Though maybe it will be another case of learning as I go along.
I'd love to hear about how you select colours. Is it something you're able to do by instinct or have you taught yourself some rules? Or do you make the odd mistake like me? Did it take you long to work out what suits you or are you bold enough to make anything work?
