What is the Red Mass?
Red Mass is a Catholic service in honor of the legal profession. The name comes from the Red gowns of the High Court Judges that attend. The observance began in England, France and Spain as early as the 13th Century. It is still observed in many Jesuit Law Schools. Many of the justices of the US Supreme Court attend the Red Mass in Washington DC.
no, color is not a mass. Color appears from the kind of lights that reflect off of an object. If you have a red cup, that means all colors except red reflect off of it, thus making it red. Light is a vibration, what you see is really a frequency. Red colors vibrate differently to distinguish that they're red. So, no it is not a mass.
