A quick refresher...please...re: exposure

If I overexpose color film does it become brighter, i.e. more saturated or more washed out? But if I underexpose, it just becomes darker, right?

Is it the same with b/w neg film, too? Am trying to get back into photo but can't remember how this goes...

Thanks!!

For all neg film (B&W and colour) over-exposure (without development compensation) results in dense negatives. For colour printed on a lab machine you get pale, washed-out prints. It is possible, as with B&W, to give a longer printing time and get acceptable prints - but there is a limit.
Under-exposure of both gives thin, pale negs with little detail which print very dark. Nothing can be done with these (although it is possible to use intensifiers on B&W negs but these only have a limited usefulness).
