validation - Validate on blur or keypress?


Is it better to give the user instant feedback that a field is invalid on keypress, or should you wait until they blur the field? The first option might annoy users if they are told their input is invalid before they've finished typing. The second could annoy users if they have to refocus a field. Perhaps a solution is to display validity/completeness (green) in real time, while delaying the display of erroneous validation until blur?
