For the British one, the people that said the British flag only has 2 colors are correct. White is a Shade. Not to mention half the people they asked looked 5.

I didn't think the British one was half as funny as the American video nor did it show people to be as dumb as the people in the American video.
To be honest I only included the link so I wouldn't be accused of anti-Americanism which seems to happen here if you're not a US citizen and you dare to mock or criticize the mighty U.S. of A.
And I'd agree with you on the 3/2 colour answer; both are valid answers depending on your perspective, after all, if someone paints 2 colours on a blank piece of paper it's not usually considered to be a 3 colour painting...
Oh yeah, and for the rednecks here before you get you knickers in a twist, an explicit qualification; dumb people exist everywhere.
