energy colors?

in the past 2 weeks i've seen a few times a bright green or gold like color while void meditating with a white around the edges (it looks like half a moon) does anyone know what this could be? or is it a trick of the mind

Normally I see a violet aura over objects, is the awakening of some part of your mind.
