a yellow square, indicating this line as the constituting ruler of the hexagram Six in the third place means:

Coming joyousness. Misfortune.

True joy must spring from within. But if one is empty within and wholly given over to the world, idle pleasures come streaming in from without. This is what many people welcome as diversion. Those who lack inner stability and therefore need amusement, will always find opportunity of indulgence. They attract external pleasures by the emptiness of their natures. Thus they lose themselves more and more, which of course has bad results.
