[This just pertains to my experience/s]

Blues and greens [occasional mixes] were always uplifting, powerful, moving, ancient.

Reds and yellows would typically correspond with pressure, the sensation of being ripped apart and/or operated on, fixed, etc. [There were a few occasions though where the initial hyperspace gauntlet gave way to this highly orgasmic red/orange/yellow fluid, like a massive lake of orgasmic jello which you could feel penetrate every level of your awareness and being].

Then a few of my strongest experiences were pure blinding white light [white as in a clear simultaneously changing infinitude of color, prismatic] and with those few experiences I guess you could say that I felt anything, everything and nothing, all raised a million-fold. "Strongest experience" doesn't even come close to what I experienced with those.  The curtains came back big-time on those ones.. [Gone for about 25 minutes in Hyperspace on those ones]

EDIT: To add to this, the color/s seemed to correspond to the architecture of the space. Hard to remember obviously, but I know with a certain degree of certainty that the blues/greens [for me] gave the most beautiful architecture in that space, often very pharaoh style pillared, snaking/twisting structures, vaulted catacomb halls, all interconnected. (though these are pale reflections of what i had seen)
