What Color Is My Hoodie?

Grey? Blue? Purple? It can look different, depending on the context. Let's talk about color perception, color temperature, and the history of laundry.

    Since the reply feature isn't working right now, I'll post a reply to Tom's post this way: you may think, it's a pointless debate, as regional spellings are fine when they can be understood no matter which one you use, but i'd argue it's not pointless, because it is a harmless, enjoyable activity for linguistic prescriptivists, and that is an inherently good thing (providing happiness to people) In conclusion, Heck you if you say Color, it's Colour!!!

    So, according to that colour sensor... your hoodie isn't gray. Or at least not exclusively. According to the manifacturer of the paint that was referenced by the sensor's software, your hoodie is... "[a] deep purple [that] has a generous gray undertone suggestive of storm clouds on a distant horizon."

    I'm surprised there's no mention of the white+gold/blue+black dress, because the colour perception depends on what type of light your brain thinks it has and therefore subtracts out.
