I believe the colored clubs you're talking about are all coin rental sets. You can rent a green clubset for 10,000 coins for a 7 day period but they're only a step above starters - nowhere near the capabilities of your current clubset. At your level, the best colored rentals available are purple MK5's for a whopping 750,000 coins/week and they, too, are likely far less capable then your current set.
Excepting your wedges, you've already paid a King's ransom for all those L0 Titleist clubs and you really won't find anything significantly better for another 30-40 levels. When you reach the low 50's you might consider the Max Spin wedges - very capable wedges at a relative bargain price. You might also consider dumping the hybrid in favor of a 3rd wedge. But for now you have excellent clubs for your level & I'd concentrate on improving your game with what you've got. Good Luck!
