I had a couple of these bi-color LED
left over from another project.

The LED driver circuit was similar to the one driving those in the other project. This is how I guessed at the 1K value. I just tested it and it works great.
Thanks,

Blue or red on a bi polar LED will be far brighter than than yellow or green so I end up putting different value Resistors behind both LED legs. If its blue up to 30k , Then a far lower value like 10r behind yellow or green.
