Red is the most powerful
the most vibrant
the most exhilarating of colours.
Red represents the blood of life, the blood of death.
Red fabrics have been used as protection in many parts of the world.
One way was to applique red fabric to the vulnerable areas of dress such as over the seams or around the neck. Red material used in this way should be more expensive than that of the garment.
