Re: looking for a particular ottoman mod
You could try Wind from the East. I don't know whether this mod changes Ottoman unforms from green to red; I know that it aims to offer a more historically accurate experience for players of eastern factions including the Ottoman Empire. In an interview with Goutlard about Wind from the East, he mentions that the unmodded Ottoman unforms aren't historically accurate and that the Wind from the East offers more historically accurate uniforms.
Another option is the Additional Units Mod. I don't know whether the optional graphics pack re-colours the Ottoman green uniform - I do know that the AUM adds Ottoman units with red uniforms, such as the Royal Constantinople Infantry Guards and Royal Janissary Infantry Guards.
Good luck, I hope you find what you're looking for.
