I don't know the meaning of an "orb" being blue. However, everything I've read about the color blue, is good, spirituallly speaking. In many cultures blue is significant in religious beliefs, brings peace, or is believed to keep the bad spirits away. Blue conveys importance and confidence without being somber or sinister, as in the blue power suit of the corporate world and the blue uniforms of police officers. Feeling blue or getting the blues represents the extremes of the calm feelings associated with blue, like sadness or depression, lack of strong (violent) emotion. I found this list of what the color blue represents:
Religious feeling
Peace
Faith
Stability
Melancholy
Trust
Loyalty
Wisdom
Tranquility
Integrity
So, I would think a "blue orb" would not be menacing. Just some food for thought.
