I woke up three mornings ago, and noticed my pillow which I thought was black and white appeared to be a beautiful light purple. Throughout the day I had the experience of purples popping in my perception. I also noticed that blues were different than I thought they were previously. For example, the icons on my phone, which I previously thought were light blue for actually teal. The Chrome icon had a tiny spot of purple that was now very vivid. I've been searching for possible answers to why this has happened, and this is as close as I've gotten. I am a color blind woman with one cataract developing. My vision is good, I only wear reading glasses I'm 72 years old. I have a doctor's appointment in a few days and I will report back here anything that I learn. Thanks very much!
