I'll say, the secret to pretty colour-blocking is using colours with the same intensity, that yet contrast each other. what do i mean? Dont use fluro yellow with dull purple, or dirty orange with fusha pink. Get my drift?
Not to worry if you don't, cos i'll help you out with pictures in this post.
Secondly, there's something else i do with dull colours, so they aren't left out to rot in my wardrobe. When you wear a dull colour head to toe, put a couple of bright coloured accesories to lift it up. For example, cream on brown, could do with a pink shoe and bag or purse (depending on the occasion). Enough of the words, let's get some pics, shall we?
