This is the second time that speech about blue has come up on a Cracked podcast (the first was a while ago) as a justification for the fashion industry and the character's pickiness, but Hathaway's character would have bought the same sweater regardless of which slight variation of blue it was. The speech is about how the fashion industry puts huge efforts into things that only matters to the fashion industry. That's fine, but it shouldn't change how the main character feels about which ever two nearly identical things that were being compared.
