Select[list, StringFreeQ[#, ":"] &]

=============
Given a simple list of strings:
list = List["Z:XBREG","Z:XBREH","Z:XBREI","Z:ZZ6P","Z:ZZ6Q","aye"]
how does one delete all the strings with a colon (:) anywhere in the string?
DeleteCases[list, ___:___] looks very logical and should work,
but of course it doesn't .
Also, there is a StringCases function which would seem
to correspond with the Cases function. There is a
DeleteCases function but no string counterpart, namely,
DeleteString function. Any reason for this?
Thanks in advance.
