Unless you're in competitive competition, it doesn't matter, although reds and blacks are considered the best for games as they're linear, but again it doesn't matter unless you take your gaming way more seriously than you probably should if you're not getting paid for it.
Browns and blues are considered the best for all around experience, they feel great and sound just as good with browns being less high pitched.
And you'd be hard pressed to find better than a Leopold, they're a great choice.
Alright then, leopould is then. And I will probably get reds since I do competitive 1 - 2 times a month. It might also help me bhop in HL2DM finally :V
