Blue is a very good color to represent Peace since it is the color of the sky that is over all of us and depending on depth and lighting is frequently the color of water.
Peace is a matter of concentrating on what we all have in common rather than dwelling on what makes us different.
Different shades and hues of a color can cause us to feel differently.
There is a whole industry based on what colors we as individuals look best in. This is rarely our favorite color but rather the color that looks the best next to our face. In other words the color we are wearing when we meet someone for the first time or have to give a speech can make a difference in how we are heard.
What are your colors and why?
