Ya’s يأس is despair, the color of which is commonly perceived as black (“in black despair”); the little brightness there may be, deep in the center, seems hopelessly blocked.
Despair يأس
"You’ll be free from the trap of your being,
when, through spiritual need,
You’re trodden underfoot, like a mat,
in the mosque and the wine house."
~ Sanâ'i
