A slightly more risqué hair trend for  fall is to add either a touch of blue,  in the form of colour highlights/lowlights, ombre, or a peek-a-boo, or a rich, full head colour. Some such hues include a deep navy, turquoise (see below), indigo, or frosty gray-blue (see above).

Deep ash mixed with faded blue is another beautiful option for this wintery look.

For the wilder at heart, a more vibrant option.

Blue also suits a variety of hairstyles and lengths.
