I am not 100% sure about what I say below, but this is how I think it works:
The cards that you turned in will not be dealt again untill all cards are used, so if you have in the three greens (regardless of whether or not you turn them in), your chance will be lower of getting a green.
(Unless right then all cards are used... which is not very likely).
You have the same problem if you do or do not turn them in, in both cases you need a new green card, so it does not really matter
There is one thing though, if you have three cards with different colours, and you kill someone to get 7 cards, you are 100% sure of a double turn in. If you have all cards of the same colour, you are only 94% sure.
So if you are really really nitpicky than you should turn in the three greens.
That being said, if you can turn in a card that gives you +2 troops, you should always go for that one, it's much more important (and even these +2 might not matter that much).
