Colour can affect our sense of well-being by altering the state of our emotions. It has the power to uplift our spirits and heal our bodies. It also changes our perceptions as to how we view surroundings. While lighter colours can be used to create more space in a room, wearing darker colours can make us appear slimmer. Magenta is said to strengthen contact with your life purpose. Pink is known to heal grief and sadness. Yellow and orange are thought to radiate warmth, joy and happiness, while green and blue are associated with harmony and serenity.
