i notice that some warming filter such as the 81 series has a little red hue on it,will the overall color of the pictures taken on negative s be affected(ie turns red)? How about others such as 80A?

The whole point of a warming filter is that it should be slightly pink or red. It wouldn't be a warming filter if it was colourless, would it?
The 80 series filters are colour conversion filters, and they all have a very strong brown-orange colour. An 80A is for using 3200K tungsten balanced film in daylight.
