Wedding Help

Comrades of r/fountainpens,

I am officiating a wedding later this summer. I thought it would be a nice gift to give the bride and groom a matching pair of fountain pens, one each in their favorite color, in order to sign the marriage certificate. The groom's favorite color is blue; the bride's is green.

Any thoughts on what pens might be appropriate? In terms of style: I'm thinking something very swirly and bright; not a solid color. I feel like there's that something Art Deco that would do the trick. I'd like to keep the total under $300. The green seems to be the tricky, part as there aren't that many fountain pens that are green.

For instance, I like Edison's Collier Blue Steel, but there's nothing green to match.

The Conklin Vintage in green is kind of getting there, but of course Anderson doesn't have on in blue. Also I'm not crazy about the crescent filler.

Thoughts?
