Regex to extract if match occurs within first N characters

I am new to regex still in learning phase. I wrote an regex expression to extract until first occurrence of a colon:

^([^:]+):

Now I want to take it one step further and limit the search to within first 100 characters. Which mean no match if match does not occur within first 100 characters and I don't know how to amend this expression to do the needful.

Check this 

(?!^[^:]{100})(^[^:]+):$

Try this:

^([^:]{1,100}):

This regex matches all text from the start of line/text to the first colon only if there is 1–100 characters before the colon ({1,100} instead of +).
