Vibrant, eh. In HSV that means 255.
I started there, but it's eye-bleeding territory, so I eased back and just got done making one that I'm pretty happy with, after reading this. Way helps with reading things, fairly similar in the end to some on
http://dwarffortresswiki.org/index.php/DF2014:Color_scheme where you can find lots.

Anyway, I used a bit of colour theory to hide the eye-bleeding pure aqua and yellow, desaturated here and there to enhance overall contrast, tried to match perceived lightness for the most part, which shifted red a fair bit into the orange. It's nicely easy to read, well, everything, and the intro movie, seasonal colours, and everything else works quite nicely. Enough inter-colour contrast to see everything on the bright backgrounds still, without eyestrain for me,
Couple of bright colours don't overlay as well as the default set, yellow on red or white on light gray is used for a couple rare things (like the title of the game). The Dark Red and the Greys could be somewhat lightened, but they're used as background walls and behind corpses and things and a much more vibrant colour there is just hard on the eyes after a while. 255/255/0 yellow and 255/255/255 white clear up those minor issues but are a little bright here and there and leave the rest of it a bit dark by comparison.
