Lana Del Rey and pink for Cancer. When Cancers enter my mind, I see pink, gentle, and kind things that comfort people. Hence the blankets and the clouds. (I don't know if Lana is a Cancer, I heard she was a Gemini, but everyone tells me she's a Cancer so I just believe shes a cusp or something. I'm too lazy to look it up.) They don't show emotion the way people say they do..they don't cry at the smallest offenses. When a calm Cancer blows up on you, it's most likely an offense you been committing for a while and they've held back what they truly feel to make people around them comfortable.
Other sides of Cancers though, the manipulation side - using emotion to justify hurting other people, is something I think of as well. Some might use selfish reasons to make other people feel bad for not consider their comforts as much as the Cancer "considers" theirs.
