- Neurosys420, the author said he knew the meaning. Please pay attention.

You are all welcome!

As I said: how could this be a coincidence? The expression only makes sense for a specific pair of meanings of each word, neither of which are the common meanings of the words.

It does if you were in the Navy.

Striking the colors—meaning lowering the flag (the "colors") that signifies a ship's or garrison's allegiance—is a universally recognized indication of surrender, particularly for ships at sea. For a ship, surrender is dated from the time the ensign is struck.

Colors, in Naval terminology, pretty much always means the flag ceremony we do each day at sunrise and sunset.

How could that be a coincidence? Taken literally on the most common meanings of "strike" and "colours", the phrase makes no sense at all; it's an idiomatic expression.
