@ChrisMayLA6@bookstodon I remember being told that white wasn't a colour but that's not true. My take: 'colour' is something the human eye and brain creates from and mix of light frequencies. White is a mixture where we can't detect an 'imbalance' towards red, green or blue that isn't dark enough to be grey, but some of us detect change 'relative' to 'normal', so white is a social construct :-).
'The Dress' (and ADHD) made me explore colour theory.
