In Hebrew, we say "pink glasses" to mean optimistic observation, and "black glasses" for pessimism. I was trying to figure out how popular the literal translations are in English. I found "rose-tinted glasses" as a popular equivalent to express optimism. But is there an analogous expression for pessimism?
Googling "looking through black glasses" made it seem not to be a popular phrase. Is this in fact a recognized idiom? Is there a similar, more common one?
