The Villanova men's basketball team celebrates its return to the Final Four after beating Texas Tech on Sunday, March 25. Villanova, which last won the NCAA Tournament in 2016, is one of three teams with blue among their school colors in the Final Four.

Go Blue or go home.

That pretty much sums up the NCAA Tournament, as teams with some hue of blue in their school colors usually win it.

It holds true for all the national champions since 2002. Red-and-black Louisville in 2013 was the only blueless team to win but the NCAA has since stricken that title from its record books after it was discovered the team violated rules. The runner-up that year was Michigan, with its blue and maize colors.

In fact, since the tournament expanded to 64 teams in 1985, the winner had blue among its colors in 26 of the 32 years.

This year, three of the Final Four teams have blue among their colors -- Kansas, Villanova and Michigan. The exception is No. 11 seed Loyola-Chicago, with its colors of maroon and gold, which already has made history by being the first team seeded that low to reach the Final Four since No. 11 seed VCU in 2011. (VCU's colors are black and gold.)
