Quick Question On Colors/Auras

When I meditate, I sometimes see the colors red, yellow, & orange in sort of a "pulse" type of motion. Other times I see the colors blue & violet/purple in the same fashion. Other times I'll see white

Can somebody explain this to me so I can begin to innerstand it?

I've been seeing them every time I begin meditation so I wanted to know what these are, what they mean, and how I can use that energy if possible

Thanks in advance, Reflections

PEACE to all the Gods/Goddesses
