Let's unpack this for a moment — starting with the claim that this colour will make you want to eat less. According to a 2012 study published in the Journal of Consumer Research, colour does play a small role in your appetite, but it largely depends on what you associate a specific colour with. So, sure — if you eat very few pink foods, the colour may not increase your appetite. But since colour association is so subjective and varies from person to person, it's hard to say that any single colour definitively suppresses the human appetite as a whole. (The colour, however, was studied in the 1960s as a way to reduce hostile behaviour in prisoners, for what it's worth.) Not to mention that having an appetite is not a bad thing. It's the thing your body uses to indicate to you that it needs food in order to survive, and suppressing that need can be dangerous. We love Kendall (and the colour pink ), but we can't say we're too jazzed about her fighting her body's natural urge to, you know, eat.
