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

All posts must be showerthoughts
The entire showerthought must be in the title
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
Posts must be original/unique

When synthetic dyes became available, people treated them a bit like we treated blue LEDs 10 years ago (sopuli.xyz)

fabric colors that were "always" available to common man were shades of everything from red to blue, white, black, brown and grays. purple was also always available, but extremely expensive.

enter coal tar era of chemistry (starting 1840s or so): aniline and later diazo dyes made fabric in all possible colors not only available, but cheap. yes initially they sucked, they ran, they weren't resistant to anything, they will give you ballsack cancer, but they were a thing. for a short time, purple fabric was a choice of the extravagant and the futuristic, and then people just stopped paying attention as it became more common

blue LEDs were sort of also used as a futuristic aesthetic choice, just after they appeared, but before these things became common, and now blue LEDs are just everywhere

Same thing happened to blue dyes. It used to be very expensive, but Prussian Blue being invented in the 18th Century made it show up everywhere cause it used to be so fancy, and then it just became a cheap dye.

Though the French loved that shit for government official and soldier uniforms, and supposedly that's why cops wear blue

there's indigo and another plant that grows in europe and also makes indigo but less, so you can just farm this thing, unlike purple dye that requires tons of work, and depending on period it was used by commoners (before 1200 or so, in western europe)

it's a bit funny to look at this today, but woad (that euro indigo) trade was a big deal, it got protected by tariffs and blockades and diplomacy, and all for nothing, ultimately both woad and indigo farming was completely destroyed by synthetic indigo production. indigo wasn't first/easiest dye to make, but it's far from the most complex thing you can cook, even in 1900s. prussian blue is much cheaper than synthetic indigo anyway
