Walter Whites Leather Jacket (flashback scene)

I've been rewatching the show for the last few days, on 3x13 now and I've noticed how what Walter is wearing in the flashback scene of him and Skyler viewing the house for the first time pertains to the colour theory, He's wearing a black Jacket, over a green shirt, over a white undershirt. Black representing death, evil deception, Green representing money, power and greed and White representing purity.

Now my interpretation of this is that Walter was always capable of doing the horrible things he does in the show, and while there might've been a slither of good in him, represented by the white undershirt. Walt didn't change throughout the series, the real Walt that had been buried for years just finally had a chance to come out.
