Kind of, you could count black as the "color" of an evil heart, too.

Looking at what religious officials often wear, black can also symbolize piety.

Most consider black clothing to be more formal, for a variety of situations.

Note that often, formal events are even called 'black tie.'

Optional is sometimes the case as well.

Pardon me as I interpost to break your team's run!

Questions arise, though, as to whether black is really black.

Rather than wearing black for mourning, some people in the world wear white instead.

Such customs are very intriguing from many perspectives.

Today and tomorrow, we will celebrate the birthday of all horses, a custom linked to August Bank holidays.

Unlike here in North America, where all thoroughbreds have their birthday on Jan 1.

Verily, the January 1 birthday can cause problems for a foal born December 31.

When horses have birthdays and bankmanagers take the day off it is a remaining vestige of the old Gaelic Lammas festival, marking high summer.

Xerses, the Persian king, must have had a lot of horses in his royal stables!

Years ago, not only in the time of Xerxes, but also as recently as World War 1, horses were used for battle as well as transport.
