Veiling” creates hidden panels of colour so that when the hair is flipped from side to the other it exposes contrasting colour. 'Blondes hiding panels on one side will create the illusion of asymmetric hair colour and brunettes can do the same with a panel of red or auburn.Dec 28, 2012

Color Veiling
This trend is more about the technique than the actual color. The top layer of hair is dyed lighter than the base, creating a see-through, veil-like effect when the darker shade peeks through, Rhys says. Jennifer Aniston is currently sporting the trend with her light-on-dark blonde hue.
