Days of the Week Since each week on a calendar contains seven days, people have assigned an angel color to each of those days, beginning with blue on Sunday and continuing through the list of colors in order until the week ends on Saturday.
Different Frequencies or Just Symbols Some people believe that the light waves for the seven angel colors vibrate at different electromagnetic energy frequencies in the universe, attracting the angels that have similar kinds of energy.
For example, they may sing or even scream to open up their throat chakra, they may dance to open up their solar plexus chakra, or they may do push-ups to open up their heart chakra.
