Red, a powerful and awakening colour. I decided to investigate the colour red. Red is a colour that comes with many different emotions. After doing my research, I found that red represents extremes. It is the colour of passionate love, seduction, fertility, violence, danger, anger, and adventure. In the Christan religion, the colour red signifies blood and spiritual awakening. Also, light red could be seen as a representation of sexuality, passion, and sensitivity.
