This has always bothered me, I want everyone to see colors the same way so we can all have the same internal experience.

However, I have rationalized away this theory with a thought experiment. Imagine someone messed with your brain and remixed your colors. So now maybe what you once saw as red you now see as green. However, since your brain has no other reference, you will not even be aware this change has happened.

Now if we put a device in your brain that changes your colors every second or so, you still won’t even know. You’ll never know! Because you have no way to compare a previous representation with a new one.

Imagine looking out now into the world around you, and being told every second your colors are being rewired. Since you can only have one dictionary of colors in your mind, you see nothing change, because that would imply there is an even deeper meta-representation of colors you can compare with.

Ultimately, colors do not exist. This is why my favorite color is black, as it is the only “true” color, and not to mention everything looks good in black.

Don't you think there is a representation of color in memory, that you can compare current visual input to? I can close my eyes and recall the image of a red apple, or are you saying my memory of red would switch to green as well?
