Not taken by the story's relation to what the color blue in the French flag "stands" for: freedom?

The commentary is pretty good. The speaker spoke of Kieslowski using "liberty" as a point of departure much like how he and his scriptwriter used the Ten Commandments in the same way in the Decalogue. "Liberty/freedom" lead Kieslowski to explore "independence."

Binoche shuts herself off from everyone, but is it really freedom or independence? She has lost her loved ones; she is free, but she really isn't.

Can one be independent and thus free if one isn't a social beast?

Blue also has a subplot or subtheme of Europe's union.

As for White, most people don't know that it's a black comedy.

"White" in the flag "represents" "equality." As a point of departure, Kieslowski took equality and crafted a story about "revenge" or "getting even" as equality.

Significantly, Kieslowski explores a nascent Poland in capitalism through the gangster/land owning plot.

"Red" is "fraternity" and Kieslowski said it's a film "against indifference."

Hope you enjoy the last of the trilogy. There's a good chance you'll like it.
