Even if your queen has been superceded, it's not a real big hassle to mark the new one. I have always just used bright red fingernail polish. When you only have a couple hives, it's not too difficult to remember the year you had a new queen, so color coding for year really isn't necessary. You just want to know if she's been superceded, and is easy to find if you need to. Like all things with the bees, your movement should be measured and paced. Not quick and grabby. A little dab will do ya.
