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. The most popular seem to be lighthearted clever little truths, hidden in daily life.

Here are some examples to inspire your own showerthoughts:

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. No politics
    • If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as "capitalism" and "communism". If you must make comparisons, you can say something is different without saying something is better/worse.
    • A good place for politics is c/politicaldiscussion
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct and the TOS

If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.

Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report, the message goes away and you never worry about it.

Applies to many other colors as well. I "understand" why that is but it hurts my brain to think about.

A few nitpicks

Subpixels would not be perfectly monochromatic unless they were laser displays. Quantum dot can get kinda close though.

if mixing light additively didn't create new colors then mixing paints subtractively wouldn't either. the results of those processes still result in light that can activate our cones with combinations of wavelengths in the exact same way.

I think the semantics of what color light is doesn't matter which wavelengths are used to produce it, but what it looks like. We don't say something is yellow because it has wavelengths of light that look yellow on their own, we say something is yellow because it looks yellow. Likewise people use the term white light all the time when there's no single wavelength that produces white.
