Wow you really went the extra mile even more than i thought for some of those details :o
And honestly it didn't feel as much of a hodge podge of periods it really felt authentic and i say that trying to acheive some authentic retro stuff myself in my games witht he same challenges of having way more colors than the limitations of the times etc... :p
thanks!
at the risk of being obvious about a thing, you may already know, that there are freely available palettes for pretty much every major game console, if you are trying to emulate a specific look (i really love the master system palette, https://segaretro.org/Palette )
You can further look up the technical limitations. For example, a SNES games base resolution is 256x224, and while it had a color range of 32000+ colors, no single sprite could have more than 16 (technically 15, as one pixel was reserved for transparency). Lots of good detail out there for any kind of hyper specific retro project.
For the ZX spectrum style project I shelved i was having a horrendous time, but a lot of good practice making readable art, because of its strict limitations (https://en.wikipedia.org/wiki/ZX_Spectrum_graphic_modes). Even worse was trying to make an attribute clash shader.
i see that this is growing ever longer with my nerd interest info dumping so i'll stop here lol.
I didn't know about that resource for palettes, so thanks for the link i'll have to check that out.
Also while i have some small knowlege on some of the limitations of older system to have a vague idea of what to aim for to have retro a retro ish style, i can only say RESPECT as of your technical knowlege here ^^ and i can only add a O_o face for the courrage you had making something aiming for spectrum specs considering the insane limitations this must have.
No worries about your info dump though it was interesting :)
