Showerthoughts

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.

In fact, yellow never exists during the entire process.

I feel like you could argue yellow does exist in HSV. I'm not a professional in programming, working with light, or using HSV so I may be wrong but my amateur understanding of HSV is that the hue strongly correlates with the wavelength of the light omitted (with the obvious exception of looping red back around into blue through wavelengths that can't exist), the saturation strongly correlates with the purity of that wavelength compared to every other (uniform distribution across the spectrum means white, then only that one wavelength is the pure expression of that color), and value is the amplitude of the resulting wavelength(s).

In this framework you could set hue to be just yellow, make the saturation very pure (high saturation), then have whatever amplitude you need (whatever value). Of course most of the time in modern computing HSV values are going to be derived from and converted back to RGB values, but for a brief period of time between computations you could argue that the computer has an actual representation of "yellow" itself and not just its Red and Green components.
