What do colors mean? Saw em while in meditation...

[Jimi]

So last night I am in deep meditation, and at about the 35-40 minute mark I hit "the zone". Heaning got muffled, hands numb, heavy-wieghty feeling in my body. Then I started seeing dark flashes of purple (eyes were closed). Sometimes they were flashes, sometimes they were shapes that kept morphing into other weird shapes, but they were all deep purple in color with a very occasional red speck here and there. My question: what are the meaning of colors (purple especially)? Is this "energy"?
It was also interesting how in the "darkness" of closed eyes, I felt like I was moving "forward" into that darkness (almost felt "drawn" into it), maybe trying to "see" what was beyond that.
Anyway, my question about colors is my main thing here.
Thanks for any input!

Purple tends to be the colour for spiritual connection.  It can highlight a psychic gift that is being encouraged or assisted.  As you felt you were moving forward in your meditation, I would suggest that perhaps you are moving forward in this area, or being assisted in this area.

The red sparks can represent physical connection, passion, strength.  I would look out for these red sparks whenever you are doing any kind of meditation or similar work, as I'm actually feeling it relates to a guide around you that is letting you know they are there.

Something similar happens to me, although, I can go just some ~30 seconds or so (Sometimes instantaniously) and I will start seeing a dim purple light, sometimes pulsing, sometimes not.

Yah exactly, same thing here.
Last night the colors came on in sunburst style. Starting like very small points and getting bigger and bigger (in circular form), and after that another smaller one would appear and get bigger, and wave after wave of this came on for about 30-40 secs. Very interesting.
