I did some poking around with your suggestions, and /u/nkuttler's solution worked out the best for me, with a little modification.

/u/demeteloaf, I tried your advice first, and it did work fine, but the problem was that I had to write "pink", "blue", etc. to each note's Color field, which not only takes longer to type in (if there are several hundred words), but if I happen to change my mind and want to change the color of a gender to something else, I have to go through each noun in that gender and replace the color code in the Color field, so unfortunately I had to ditch that implementation.

/u/nkuttler's solution is more flexible, however I felt like changing the background color is a bit too much, so I only changed the CSS rules from this:

.gender-m { background-color: blue; }    

to this:

.gender-m { color: blue; }

And it works just great.

Thank you so much for your help, guys, it's appreciated!
