Color, beyond what it is, it's the thing we all seem to have an opinion on. I remember teaching a class and a student said she had hated the color green. At the time, it didn't occur to me to ask why, but I suppose it is because she equated it with an unpleasant memory. An interesting thought, to eliminate an entire color based on a feeling. One that may need to be explored, perhaps?
I can confess that color is an area where I tend to show absolutely no restraint.
Maybe something to consider in this month of colornessness. To make work with no color or at least to limit the color choices.
