The prefix for "bleak" is "un-." The addition of the prefix "un-" changes the meaning of the word to indicate the opposite of bleak, which is typically something more positive or hopeful. Prefixes are morphemes added to the beginning of a word to modify its meaning, and in this case, "un-" serves to negate the original meaning of "bleak."
