Well, for starters, azure, cerulean, cobalt, sapphire, midnight, turquoise, and indigo are all there already. Prussian blue is made with cyanide, so that might be what you mean by cyanic blue (unless it's just cyan). It's very similar to midnight blue, though, to the point that they're probably not worth using together.
Also, unless you're also asking how to color-code using the forum's bb script, I'm not sure why this is in Board Business.
