To get some intuition around saturation and lightness, try out a color wheel. Start with a color like #A68768 and then play around with the saturation level (labeled "S" in "HSL"). Have fun!
No worries, color is complicated and fascinating!
"Brightness", in my experience, generally refers to the amount of light reflected (or sent from the light source). It doesn't directly affect the perceived hue, it's just a measure of how much light there is. It's hard to get an intuitive sense of brightness, because of how we perceive color.
Saturation refers to the "purity" of the color--that is, how much light it reflects of other wavelengths. Gray reflects visible light in equal proportions, which makes it the least saturated. A surface that reflects only a single wavelength would be considered fully saturated, and appear as a vibrant hue.
It might be more helpful to think about how our eyes receive different wavelengths. There are three colors we perceive: red, green, and blue. The closer the reflected wavelength is to these colors, the more those "sensors" in our eyes are activated. So for example, yellow activates the red and green sensors about the same amount (and less than pure red or pure green), so we perceive yellow. Orange is mostly the red sensors, with a little bit of green activated as well.
We perceive brown when the blue sensor is also activated by some amount, because brown reflects a little bit of blue light (as opposed to "pure" orange, which wouldn't have any blue light reflected). The lightness/darkness of the color is mostly the overall amount of light reflected (the brightness), but the big difference in what we perceive is that little extra blue light that brown reflects, that orange doesn't.
Brown is still considered "dark orange" because the primary wavelength that it reflects is an orange color. And dark browns don't need to reflect any blue light to be considered brown. But lighter brown shades will reflect a greater proportion of blue light than "light orange" would at the same brightness.
If by "light brown" you mean like a tan or khaki color, it would have to do with saturation--that is, sort of "watering down" the color with some blue tones. Neutral colors like gray and brown typically have a mix of a wide variety of colors, gray being the "true" neutral and brown being a bit heavier on the red/yellow tones.
Yeah, I've had some issues with Nemo as well. I ended up installing Thunar and have had a much better experience with it. And you can set it to be your default file manager if you like it.
Getting games to work can be a little tricky, depending on the game. Be sure to check out protondb for comments that others have. Sometimes it's just a matter of changing the version of proton. Not sure about the other usability issues you're describing.
Do you have an Nvidia graphics card? If you do, and if you haven't already, you'll probably want to use the proprietary driver instead of the open source one (which is selected by default). That might even help some of the Steam issues.
It's not a matter of freedom, it's a question of desired functionality. If anything, keeping your data in a sandboxed area by default respects your freedom more (that is, freedom from other apps scraping your data).
If it's on Github, you could file a feature request to have that default behavior changed.
Assuming you're on Android, this is coming from the OS. It's still possible to save data in an externally-accessible place, but the default is storing things privately for each app. It's annoying for use cases like yours, but it's arguably better for overall security.
In as much as it pertains to me, I don't tolerate it. Otherwise, if people want to bullshit their way through their career, I don't really care. This happens in every company that has more than one employee (almost).
If someone else starts ordering me around when they don't have the authority to do so, assuming it would change my course of action, I'll tell them politely that I might be able to get to that when I have time. If they escalate it, I tell them to talk to my boss about rearranging my priorities. And if they do that and succeed, that's fine. Once you establish that you don't report to them, I've found they typically leave me alone. If not, I talk to my boss about it in private.
