People from different cultures have different conventions for answering seemingly innocuous questions like this. Users will become frustrated if when you ask for an email address, for example, if the response box only allows for 20 characters.
Use colour strategically. Colour in forms should be used with care - but used well it can really aid form completion and navigation. In general, yellow, for example, is a colour to avoid as much as possible - text set in yellow on a typical light background can be very hard to read - and people can find yellow aggressive.
Progressive revealing, when implemented well, progressive revealing gives interactive forms a head start over traditional paper forms. When asked a particular question in a form it may be the case that, depending a users response, they are asked a set of specific sub-questions, or alternatively routed to the next appropriate section of the form.
Provide examples of the sorts of answers you are looking for, and where appropriate, provide guidance notes as near as possible to the question they relate to (i.e. in the actual form).
