Hi,
A while back we had a thread on Pritt's Greentail (pattern 33 of his list), which is a softhackle grannom fly immitation.
Body: rear half - green floss/sild (emerald green; so dark green, not bright)
: front half - grey (lead coloured) thread lightly dubbed with hare's face fur
Hackle: inside of a Woodcock's wing, a Partridge's neck, or under a Hen Pheasant's wing
I suppose since the greentail represents the egg sack on these flies (at least on the UK version), so this wouldn't really be an emerger pattern but rather an egglaying female caught in the surface film (or just under).
Anyway, we experimented a bit with things in that thread and I think the consensus was that waxing could help to darken up some of the green therads/silks if they are not dark enough (but check them wet first, as some materials will darken when wet). REE had some really nice ones as I recall.
This was my version:
