A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. Avoid politics
    • 3.1) NEW RULE as of 5 Nov 2024, trying it out
    • 3.2) Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
    • 3.3) Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct

When describing color temperatures, the "warm" color tones actually have colder temperatures. (feddit.org)

So lets say if you compare the color temperatures of 2500 K vs 5000 K, the 2500 K would have more red light and usually is described as "warm" light, even though it is called a lower temperature at the same time.

(Yeah I know the color temperatures in Kelvin have smth to do with black body radiation, but I wonder if the red light = warm and blue light = cold has some evolutionary background or that blue light has been discovered wayyyy later (blue LEDs etc.).)

Also in low light, our eyes are more sensitive to blue light, so moonlight (though not necessarily the moon itself) appears bluer than sunlight. Especially in contrast to nearby fire and coals.
