In my opinion, theoretically, once dead - you are no longer
binded by Physical Law. Therefore, if, you can "see", very likely
there will be no color. Because LIGHT belongs to the living world
where Physics rules. Without light, color cannot exist.
Also, there will be no smell, no sense of touch, no sense of
gravity (weight),
no sense of temperature, no pain, everything that we experience
alive will not be present in the after death realm - if it
exists.
Am I making sense?
I think a lot about this topic of death.
