In case you did not want to have to keep checking them with a battery I suggest:
using a piece of tape to stick the legs to and write on the tape what colour the LED is
alternatively a labelled cup works to.

Side note: roll the tape up and this will make carrying LEDs in your pocket easier as the legs will not stab you.
Haha, do you carry LEDs often?
Of course! <br>I also always carry a tape measure and a spare 3v battery because you never know!
