Color Symbolism and Meaning
I found this list in an old book.The reason why this may be of importance is pretty self-evident: if you have a message to communicate the colors can be used as an additional code. This can be done with jewelry, flowers and art pieces. However, most people these days will need an explanation of what a particular color means. So perhaps this is something that is better saved for clandestine messages or something that is only supposed to have a strong personal meaning for just one or two people.
