Interesting video of a colorful Orb captured over Gdańsk, Poland on March 9, 2015.
Many paranormal investigators do not consider orbs as paranormal evidence because there are too many natural world explanations for them.
However, it is a possibility that some orbs could be paranormal in nature. This may be particularly true of orbs seen with the naked eye, especially those that appear to have their own light source and unusual patterns of travel.
For example the light source of the colorful Orb over Gdańsk is green and reddish.
From a spiritual perspective red and orange colors are associated with safety and security, as well as a sense of belonging. Some paranormal investigators believe that a red or orange orb is a sign that an entity has assumed the role of a protector. This could be someone who was charged in life to keep watch or be a caretaker.
A green color is associated with the heart. It is also associated with nature. Green orbs are sometimes thought to be an indication of the presence of a human spirit, as opposed to one that was never on Earth in human form.
