We survived a long time seeing in UV, which is common to many species today. Color is a pretty recent phenomenon (recent in millions of years type timeframe) but some very ancient written texts seem to indicate maybe as late as even 8,000 years ago all colors were not as apparent. It is hypothesized by some that there are some (mostly female) humans who have 5 primary colors as contrasted with the 3 commonly accepted (meaning a few people may actually be seeing “tints” most of us are not seeing). There is no reason to assume (you are “that” kind of medium) what the visual sense, or any of the senses, outside the experience we are in right now is the same.

Motives for pushing changing popular neutral shifts have to do with selling paint and painted things. Ask a spirit that seems friendly if they still likes same smells and colors, I’d be curious. For that matter since I have limited experience with out of body to people good at remote viewing always see in color and have same preferences? I dream in color and in UV (I thought I was having black and white dreams till I looked at stuff through UV lens).
