| Jun 14, 2019 at 19:21 | comment | added | Monica Apologists Get Out | It can also be that humans get red when we're hot and blue when we're very cold. There's a lot of ways this association could have become common. | |
| Jun 14, 2019 at 15:39 | comment | added | Acccumulation | The reason red is considered hot while blue is considered cold is that hot objects can radiate red light at easily achieved temperatures, while radiating blue light requires extremely high temperatures. Thus, we routinely see red as radiated light, while blue is almost always reflected light. | |

| Jun 13, 2019 at 20:03 | comment | added | BlueRaja - Danny Pflughoeft | I always assumed the color association comes from the day/night cycle. Ambient outdoor light is "warm" colored midday, and gets cooler towards the evening or on cloudy days. | |
| Jun 13, 2019 at 15:43 | comment | added | Brad | @nigel222 I somehow doubt that plumbing is the source of this convention though. Rather they are another adopter of an older convention (fire and ice are older than hot and cold water lines) | |
| Jun 13, 2019 at 13:16 | comment | added | nigel222 | @Brad: its a plumbing convention: blue for water, red for danger (hot/boiling water). There are other colours for pipes with other things in, such as compressed air. | |

| Jun 12, 2019 at 21:56 | comment | added | Brad | @Tashus Frozen lakes, glaciers, generally really thick ice looks blue. Thin ice like ice cubes isn't thick enough to really notice. | |
| Jun 12, 2019 at 21:48 | comment | added | Tashus | @Brad I don't know where you get your ice, but mine tends to be clear. | |

(red = warm, blue = cold) are even the opposite to what you'd expect from a physics point of view. maybe for fire. blue fire is hotter than orange/red fire. But ice is blue which is where I think the "cold" comes from.
