Altered Color Perception
Aside from my abnormal sputum production and torso pain (which I posted about in other groups), a new issue with my vision has developed in the past several days where, when I wake up things are the wrong color (white pillows are neon blue and green, or the ceiling neon yellow) and it lasts 1 or 2 seconds and then the pigmentation shifts to normal -- bizarre. It has happened the past 4 mornings and also when I open my eyes after lying down in acupuncture. The shapes and clarity of objects are fine, but the color off. Has anyone heard or experienced this? Today I saw an ophthalmologist who examined me and said that structurally everything looked good.

@kongtengco What you may be describing is retina fatigue which is normal. There is a lot of chemistry that happens in the eye to be able to convert colored light to a nerve impulse to send to the brain. Here is how to demonstrate this phenomenon. Stare are something of an intense color for a few minutes, then look at a white sheet of paper. You will see an "after image" of the shape in a different color.
Having your eyes closed if you were in sunshine, may have looked red because you are seeing the color of your blood when light passes through your skin of your eyelids. You brain started supplying green as the opposite color to ease the fatigue of only red, so when you opened your eyes, the greens were enhanced.
The primary colors of light are red, blue and green. Color vision comes from "cones" which are nerve endings on the retinas. Nerve impulses involve neuro-transmiters which are molecules that have to cross the gap between nerves to send the impulse along the the path to the brain where vision is interpreted, so your retinas have to do this and this process will fatigue with constant stimulation. When the cones for a particular color fatigue, they are less sensitive to that color which makes the opposite color of light more effective because it's opponent has fatigued and kind of quit the game. This study describes this effect of chromatic adaptation in a blue vs yellow color shift. Blue and yellow are opposites for light colors, and all colors are present in white light. When you see a rainbow or use a prism, the wavelengths for the different colors are separated and displayed. See page 13 of this study for a detailed explanation.

Also how colors look also depends on what color is next to it and the same color looks different visually when placed next to different colors. I am an artist, and that is something that I learned in my training.

I experience it quite often.
As I wrote many months ago, when I have been in a darker area, such as the house, and then go outdoors, i.e. bright light, I will see tiny blue stars on the grass, in the bushes and in the trees. . esco203@comcast.net
Having the same problem, it did stop and started back again recently when I stated using my inhaler again. So, now I have something to give the doctors to figure this out. It only happens when I wake up and the walls are a totally different color for a second or more, never the same color, I notice patterns in the colors this time, also bolder colors.
@gogo40 I you scroll back a few posts, I explained what happens with retinal fatigue and that does cause colors to change. It’s actually very interesting.
