Yellow

Yellow is truly joyous and virtuous in its purest form, making it the most widely used colour in the world. Yellow exudes warmth, inspiration and vitality, and is the happiest of all colours. Yellow signifies communication, enlightenment, sunlight and spirituality. It is also associated with wealth, being the colour of gold. In rooms to the north that lack a strong source of natural light, walls can be painted yellow to give the rooms a bright look. Yellow is an ideal colour for classrooms because we learn most effectively in yellow rooms.
