You may remember some time back, we retweeted a post from Leighton Denny himself where he answered the age-old question: “What is your favourite nail colour?” His answer was immediate: Steel Appeal. A slightly shimmery gunmetal grey colour, it is my favourite colour now too. I tend to generally like zany nail colours, but this shade is really a great way to wear a dark shade that appears more neutral than a simple black might. The slight metallic shimmer gives a sense of dimension and depth to your nails, making them look like they just came from the salon. Two coats of this colour gives the full effect.
