The colors orange and black can be traced back to the occult. They were connected to the commemorative masses for the dead, which were held in November. The unbleached beeswax candles used in the various ceremonies were orange. The ceremonial caskets were covered in black cloths. So thank the Druids and the Celts for them.
Feng Shui-wise, these two colors are on the opposite energy spectrums, so to speak. Orange is a very lively and happy color, the color of fall bounty and the warmth of fire. Orange is often called the "social" color, as it creates the feng shui energy to promote lively conversations and good times in your home.
Black color, on the other hand, is the color of mystery and void. The color of a space with no beginning and no end, a space with an infinite creative energy incomprehensible to the human mind. Full of the feng shui energy of mystery and sophistication; black color also holds the energy of power and protection.
A perfect combination for Halloween.
