Yellow, green, pink, blue...

Some days, many Thai people will wear polo shirts of the same color. I don't understand why, except that I know certain colors denote support for the royal family. I also heard that the King was once photographed exercising in a pink collared shirt, which is why most people wear one while they are working out at the Rama VIII park I like to run at. I've also heard that days of the week are associated with colors, though I haven't been able to correlate certain days with specific colors.
