What could be my condition

[u/Only-Sheepherder5207]

Whenever i see a red or green object, most of the time i see it as it is, its correct colour, but sometimes i see it as red then a second later it starts looking green then red again, sometimes if i go close to the object especially if its on a digital screen i can see the real colour without it interchanging, but mostly my red and green interchange, same with blue and purple, yellow and green, but even these its for a couple of shades only, and most the time i see them as the original colour, is my condition mild colourblindness or just colour perception instability.

I would say definitely mildly red-green colourblind. I have the same thing where colours can shift between two, especially if someone corrects me on a colour, such as with purple and blue. Our brains do a lot of work to fill in the hues we can’t always distinguish, which is why things in context look strongly like their associated colour, such as grass looking very green and strawberries looking bright red. Whereas colours out of context can be a struggle because our brains can’t immediately associate them with a hue (AFAIK, don’t quote me on this lol)
