I can't find anything about it on google and I have 2 days till my next therapy appointment to ask a professional, but I'd like to ask you all.  


Yesterday in a PT appointment there was a green wall that appeared to change color to red when I started derealizing. I saw it as red when I was zoning without realizing it, and caught myself being confused over the color for just a second before snapping myself back. I remembered it was green but definitely saw it and believed it to be red for a second. If I didn't keep snapping myself back to attention I would immediately zone and the wall would change color.  


I feel like the color changing thing has always been there when derealizing, I've just never had a clear example like this that made me question myself.  


searching for info about cones and inverted colors is leading me nowhere.
