I think most normal is consistancy and color of melted chocolate, but a tad thicker. My 13 Year old expresses nuclear green, even after AB's. Some are watery dark or light brown, some have dark or light specks in it, some are cream colored and slimey. Some of the Techs use dental rinse on a gauze to wipe the butt afterwards to kill the odor. I don't get where ppl say once you start expressing the glands, you'll have to do it all the time. If they are clogged and filled, if they are not expressed, they can burst and require surgery. My older guy has occassional problems with his, I may have to express them 3 times or so over the course of 2-3 weeks, and then they return to normal for months until he gets clogged again. I wouldn't risk not expressing them when they need it.
Also wanted to mention a lot of dogs will try to hide under furniture or in a corner when their glands are bothering them, some get shakey, and act real nervous and don't want to be touched or petted.
