Never seen green , only the red and yellow , it was a bright yellow as well rather than off white . We use a unscented soap bought from Salisbury's at home too due to the wife having sensitive skin and perfumed soap bringing her out in a rash ( She is a ginger and moonlight/sunlight does the same )
Can't say I've seen it mentioned, last one I saw was in 2014 in an SQ's store in the disposals pile.
If they are still in service I don't think they get taken out much, if at all, and I'm sure the only people that would know how to work them are the sorts with jobs that don't go anywhere that the use of one would be required.
When did the Webley and Scott No4 flare pistol go out of service? I used to have to check them and the flares when servicing the Hercs. I’m sure they were still fitted in 2003 when I was posted from Lyneham and were removed when posted back in 2009.
