I enjoyed watching the phone call between Don and Megan from Season 7, Episode 7 of Mad Men because it is so obvious that THEY ARE IN DIFFERENT PLACES!
Don is in a ridged, dark, conventional world with heavy drapes and dark wood. The chair he sits in reminds me of the chair in House of Cards. It is very traditional, but with unexpected whimsical woodwork.
Megan, on the other hand, is in sunny Los Angeles (a city very dear to me). She is sitting in a cord chair in the sunshine, surrounded by west coast potted plants and a California color pallet. Honestly, things haven't changed too much here. This is what it looks like.
