Opinion on Damsels

I have avoided getting any damsels due to their aggressive behavior....but, the wife would like me to get a "group" of schooling fish with "color" and lots of swimming action. Green chromis are nice, very available, but not enough color (for what she's looking for). Blue chromis would be great, but you can't find them (unless you order online and I'd like to avoid the shipping costs). So, that takes me back to damsels... color / schooling / action....but, potential nastiness.
I currently have 2 Ocellaris clowns, yellow clown gobie (tiny guy!), sailfin blenny, royal gramma, and a banggai in a 60g. They all are peaceful and get along pretty well....well, except for the royal gramma who opens his mouth really wide and acts very ferocious, but never causes any real trouble. I'd hate to put a group of aggression in the mix and cause a big problem. I've read on other forums that Starcks damsels are fairly peaceful, but they're also $30 each.
or...maybe it's not a big deal and adding damsels would be ok....
Any thoughts or suggestions?

 

Thanks for all the comments...
1) I've not seen green chromis under actinics. I've shown my wife pics and she said "not enough color"...but, I might have to reconsider - I personally like green chromis a lot - she wanted a reef tank in her kitchen, so I try to defer to her wish list.

2) The Anthias is a great idea that I had not really considered....thanks Nick. They're harder to keep than Damsels, obviously, but would be worth the challenge. Biggest issue I can forsee with them is that I've read they should be fed multiple times a day....I feed only once a day. Not sure if that's really a problem or not.

3) The comments about the yellow-tail damsels being less aggressive than others is good to know....however, Troy's comment about damsels becoming more aggressive as they "mature" is what concerns me...I think adding fish later would be difficult with them in there.

4) Nick's comment about damsels not truly being a schooling fish is good to know too...sort of makes sense though....they "group" probably cuz they spend all their time chasing each other.

5) I think the comment about damsels being like the "terriers in the dog world" is a good observation... I'm not a big terrier fan either ! I'm afraid my little yellow gobie would be lunch - he's about as docile as they come.

6) Really interesting comment about the Blue Chromis...."big" and "aggressive". I knew they got bigger than green chromis, but the aggression is surprising....thought they were supposed to be peaceful. Their coloration is very cool though.
