Color!

The site that I found that was monochromatic was http://www.yankees.com
It basically sticks to the dark Yankee blue.
Pretty much any team website is monochromatic because most teams have one signature color.

The site I chose for complementary colors is http://www.nbc.com
It uses the colors blue & yellow and I think it looks really good.
Not only does it look good, I can watch my favorite show, The Office on this site whenever I want, so that’s always good.

http://www.ym.com is a site with a triad color scheme.
It mainly only has the colors white, purple, and orange.
It’s pretty basic and simple, but it looks good.

http://www.tutorialized.com/tutorials/Photoshop/1 was the site that I think is closest to being a analgous scheme. It mainly features a few different shades of blue, and grey.
