Colours themselves do not “mean” anything, yet the society had led us to believe they do. A lot of colours have meanings connoted with them, such as red means “stop” or “danger” with the most common example being on a set of traffic light.
But the connotations of the colors, what we associate watching at it, can also change from culture to culture.
One of the main example is the color white. People who lives in Western countries associate this colour to brides and weddings but also to angels and peace (white doves). In general means purity and cleanliness.
The feelings that habitants of Eastern counties prove when they see the color white are opposite, they think about death (funerals) and sadness.
If we go in India, Japan or China we will probably see people wearing white dresses at funerals, but usually for Catholic and Buddhism countries the main feeling that the white colour transmit is purity, elegance and innocence.
