I came across this recently and although it's now 5 years old it's still a brilliant idea.
The Outdoor Advert titled 'Natural Red' was done by H&c Leo Burnett advertising agency for Koleston Naturals in Lebanon. It was released in Feb 2008.
The creative billboard Campain for Koleston Naturals utilizes this natural beauty to illustrate the fact that this women’s hair dye is made from natural ingredients.
The billboards are strategically placed on a road side cliff with an unspoiled view of the sea and beautiful skyline.
The woman’s hair area in the billboard is cut as to capture the variations of this beautiful scene during the different phases of day and night, reflecting the variety of colors that Koleston Naturals offer.
The hair transforms from bright yellow to fire orange during the day. Once it starts to get dark, the billboard lights up, producing purple and vibrant coloured hair.

Excellent use of nature to promote the charcateristics of the product, don't you think? I love this innovative concept!
