From what can research, my color blindness seems to be atypical monochromat, that just means I see greyscale with some color. In my case, I see colors if the hue was strong enough. I also had trouble seeing low light conditions. Meaning, I could see outside okay but inside and at nighttime, everything was much darker than it should be. A nightlight that would give out a warm, yellow light would appear to me like a very pale yellow, almost a cold white light.
I've seen weird things due to low blood pressure, it's weird in a different way. Since I'm resistant to fainting I've seen stages of vision before I pass out. First there would be a yellow tint to my vision. then the yellow would be replaced by more intense magenta hue, and before I would pass out I would just see white with black blobs which were supposed to be shadows or my vision just turns black.
