I only started watching "Breaking Bad" a few weeks ago, and having raced through the first two and a half seasons in a week then watched the remainder of the third season at the usual weekly pace, I'm only now experiencing my first withdrawal from the show. To take the edge off, I thought I'd write a series of posts about the show's use of color.

Tonight's pre-credit sequence flashed back to a young househunting Walt and Skyler looking at the house they'd soon buy. The season's recurring theme of Walt as a man of caution is turned on its head, with Walt scoffing at the three bedroom house as too small. When Skyler suggests it's as high as they can go in their price range, he asks her, "Why be cautious?"

In last week's episode of "Breaking Bad," there was a curious moment just before Walt got his dinner invitation from Gus. As Jesse was about to open a valve that would release toxic fumes into the lab, Walt had to remind him to put on his mask.

Among Georgia O'Keeffe's numerous painting's of her home's patio door, two 1954 companion works differ only in their use of color. "Black Door with Red" has vibrant reds and yellows contrasting with the black doorway in the center. In "My Last Door," however, the red background is replaced with white while the yellow accents become shades of gray.
