I would hate to just see in monochrome.
Now that you know what colors look like and what a fun it is to see colors, yes, I would hate it too. But so many are born color blind, so they have no idea, they only know black and white.
As far as being blind to certain colors, I am one of those that has trouble differentiating different shades of green and brown as well. Shades of blue also give me challenges.
Have you been diagnosed?
