This could be the regex you’re looking for:

b[ws]+(?=:)

b world boundary;
[ws]+ matches any word or whitespace (at least one character);
(?=:) positive lookahead that specifies the word must be followed by a punctation mark;

If you want to get the ":" too you can simply remove the lookahead:

b[ws]+:
