In what way is blue hour considered considered especially flattering for people with blond hair?

The blue hour comes from a French expression (l'heure bleue) which refers to the hour experienced between the hours of daylight and darkness. The time is considered special because of the quality of the light at this time of day (also in photography; it is considered especially flattering for people with blond hair) and because in the summer, this is often when the smell of the flowers is at their strongest.

probably, because their hair is light, and you can still see them at this hour, I never heard of this before and it is interesting, thank you.
Reply:wow never knew that. I don't think blond hair should be a factor and most french people dont have blond hair.
Reply:This is really interesting stuff. I think it's because blonde hair is fair/light in colour. :-)
