I'd have to say the Red Lantern Corps. There power is pure, unchecked, unstoppable rage.

I'd say the Indigo Tribe because they seem to be able to channel the powers of any other lantern.

Beige. Its like the second equal strongest color white, but browner. Or its like the second equal strongest color black, but browner. 

White.

Blue is said to be the strongest in the spectrum. hope can be truly unstoppable if people use it the right way

i know

My opinion: Black Lanterns.

White as shown recently has to be the most powerfull.

If we're excluding White and Black (which are technically not colors), then I'd go with Orange pre-depowering.  
 
I'd also specify if we're going on a single Lantern basis, or by the entire Corps of each color. 

Indigo and recently white one as ls said previously.

Individually i guess the white lantern.

caucasian doesn't mean white btw. I don't know why people think it does since it means a person whose origins are the caucus of Asia. ;p  Orange is also pretty strong too considering you are basically a one man corp/army.

Well Sinestro was the most powerful as the White lantern, even though all colors combined in a spectrum would be Black. I guess they didn't want to make a rainbow lantern.

Not sure there is one, all the colors are equally powerful just different.
It is up to the warrior, not their weapon.

Orange, only because the power is not being shared by multiple people and just one person uses the power, plus the entity is stored in the battery for additional power.

White and Black
 
Not counting life and death
Red offensively
Blue Defensively

Red would be the most powerful, but it is uncontrollable. Green is more well balanced.

I thought the whole point was that they all balance one another out?  Like an elaborate scissor, paper stone system except for the 'meta' rings like White and Black?
 
So things like 'hope prevails over fear but hope is useless without will' etc make sense.

Indigo's don't need a lantern around for them to use their powers do they? John Stewart recently used the Indigo ring to turn into a black lantern and there weren't black lanterns around.

Who were beaten by the White Lanterns.

In terms of power, the indigo tribe is the most powerful solely because they can use other Lanterns powers themselves. Now, in terms of singular power, Larfleeze is the most powerful because he has all that power to himself.

Blue really isn't much of a defense against anyone other than Red or Orange since they can negate them, but even still they are pretty useless on their own without a Green Lantern.

I like that about them. They're not there to police the universe like the Green Lanterns. They're more there to inspire people. They aren't a combat corps.

I completely agree. I love what they stand for and the power they have when a GL is present, but in this discussion they are not the most powerful alone. 

@Kallarkz: Well, unlike the Blue lanterns, the Indigo tribe can use their own rings to do use projections and almost everything the other spectrum colors can without needing another lantern near them, but when they are in the same vicinity as another lantern, they can use their power. All of this, of course, is well known to anyone who keeps up the the Lantern Families or is into DC at all. The cool thing about it is, they can use any extent of the power as they wish and they don't even have to be a veteran Lantern of that specific color. John Stewart had the ring for like, not even a day and he blew up Mogo when handling the death spectrum for the first time. That is a HUGE feat that no other lantern can do considering Mogo is arguably the strongest Lantern and the heart of the Corps.

there most powerful once you combine them...

Each of the Lanterns showed extreme proficiency when using the rings of the other Corps. 
I have not seeing anything though that shows that a Indigo Tribe member can mimic the powers of other Lantern Rings...What exactly would there be to mimic anyways that is not inherent to all the power rings? Most power rings can heal, create energy constructs, force fields, communicate..etc. 
In what issue did the Indigo tribe show the ability to sync with other lantern rings and then use that rings unique abilities?
