In Thailand, the days of the week have colors assigned to them:
Sunday is red.
Monday is yellow.
Tuesday is pink.
Wednesday day is green.
Wednesday night is gray.
Thursday is orange.
Friday is light blue.
Saturday is purple.
So: today is colored orange.
The color assigned to a person is the color of the day of his birth. The King’s color is yellow, which is why there are so many yellow flags seen everywhere.
