This answer is directed towards women, because this is a common occurrence for them and not men. If you are a man and are having a stretchy discharge that is colored then seek medical assistance. Regardless of pain or odour, discharge other than urine or semen from the male member is not meant to happen and strongly indicates an infection.
However, this does happen to women quite often. Generally mucous is produced when a woman is ovulating. This mucous should be clear or white, or an in-between creamy color. It is fairly viscous (i.e. Not entirely liquid, like PVA glue) but should be odourless and not overly thick, thus retaining that stretchy property. If it is strongly white and quite thick and possibly with odour it would suggest a yeast infection.
Yellow and green or either of them singularly would suggest infection and you should go to a doctor or clinic. It could be very minor, and as previously mentioned the telltale signs are any hint of a foul smell and the thickness, which if an infection would represent something similar to cottage cheese.
If your discharge is brown this is most likely old blood and is occurring post-period. Another occurrence is for the mucous to be light and watery. This is often a result of exercise and depending on the exertion can be quite heavy. Of course, these possibilities all differ per person and their genetics. Some people fight off infection better. Some people handle exercise better.
