Blue has a smaller wavelength than the other colors, so… It has a larger frequency than any colors.
And its all about the frequency that matters…
One of history’s greatest engineers Nikola Tesla, who invented the means to transfer and distribute electricity over the long distance, once said, “If you want to find the secrets of the universe, think in terms of energy, frequency, and vibration.”
The same holds true for the world in which we live, our interactions with each other, and indeed our interactions within.
Blue contains the properties of disinfection, inhibition, and cooling and placating. Violet a variant of blue is an amalgamation of all the properties of the other five pranas.
Blue also represents meanings of depth, trust, loyalty, sincerity, wisdom, confidence, stability, faith, heaven, and intelligence. The color blue has positive effects on the mind and the body.
Hence, we chose to be Blue.
