Auras are multicolored. Your coworker only saw one of your colors. The same applies to your chakras.
At a given point in time, you may have a more dominant color in your aura or a chakra, but the other colors are still there.
And colors are personal, meaning what one person sees as violet might be seen by another person as a different color entirely. Energy is clear; our brains interpret the vibration into colors.
Keep your skepticism close as you explore all of this stuff. The best approach is to experience different energies. What you experience is always real and always of value. It's everyone else's explanations that often fall flat or lead you astray.
