teal. its just the darkest one.
i use the pink one! simply because i think its the prettiest and goes best with the coding for one of my characters~
I use the light pink one. Just in a pink mood.
(But there are some downsides like there's this one code warning that's unreadable with this theme.)
Even though I dislike the color pink, I use the "pink is just the best color" theme because it is literally the only one that doesn't hurt my eyes, I can use default too but it's too plain and boring.
