Fashion's blue period: How cobalt is the hottest new hue to sweep the red carpet
I always thought cobalt was a darker almost blackish-blue. These colours are blue but more a hue of electric blue almost royal blue but certainly not cobalt.- Amanda Martin. – Actually Amanda, cobalt is a bright blue and more on the lighter than the darker side. It is a little greener/cooler than ultramarine. Not that you would call it blue green by any stretch of the imagination.blake Lively's dress or Liv Tyler's are closest to actually being cobalt. Perhaps you are thinking of Prussian blue which is a dark rich blue or Payne's grey which is ultramarine and black. These dresses are all blue but not all cobalt. Some are ultramarine, cerulean, French navy and plain old navy. I wish fashion writers would learn a bit about colours. – Someone who knows, Reality, 07/7/2011 04:48Oh this reminds me so much of Miranda Priestly from Devil Wears Prada! :)"what you don't know is that that sweater is not just blue, it's not turquoise. It's not lapis. It's actually cerulean."
