I like the look of vacuum-fluorescent displays (VFDs) -- a high-contrast display with a black background, solid color areas. Enough brightness to cause some haloing spilling over into the blackness if you were looking at it. Led to a particular design style adapted to the technology, was very "high-tech" in maybe the 1980s.
OLEDs have high contrast, and I suppose you could probably replicate the look, but I doubt that the style will come back.

EDIT: A few more car dashboards using similar style:

And some concept cars with similar dash:

Some other devices using VFDs:

VFDs are the shit!
Newer, but I quite like the gentle amber LCD (not LED) displays of my car. At night it’s bright enough and sharp enough without being visually loud. I wish more of these displays were still being made, I’d love to use them in car-centric Arduino projects and data displays that would be consulted at night or that sort of thing.
I always ask my friends “How the fuck do you live like this?” when I hop into a car and the music UI is a garish color searing itself into my retinas permanently.
Thankfully, advertising companies have identified this marginal comfort I find in the warm interior lighting of my car and have proceeded to mount insultingly blinding screens all over the city.
The city being the midrise urban sprawl north of Beirut. What do you mean regulations on brightness habibi? You think you live in Paris? Imagine this: half the street is unlit because the power is out, but the advertising company’s invasive bullshit budget™ has enough foreign cash to burn to keep generators running all night for these shitty ads. Gotta beam an extra few kilowatts of photons straight into this sleepy driver’s eyeballs while they operate a motor vehicle, on a highway that a lot of people cross by foot. There’s a special on fish at the fancy supermarket, how will I live without that knowledge?

Not sure if you mean VFDs or amber LCDs, but Matrix Orbital sells both sorts in small quantities that you'd use in a project and can interface to a microcontroller -- I was interested in them myself when looking for small VFDs, years back. They're going to be segmented alphanumeric or grid displays, though, not things with physical custom display elements like those car dash things, but that's kinda part and parcel of small-run stuff.

Just choose the "amber" option if it's an amber LCD you want.
Can also get their displays via Mouser or Digikey.
That’s exactly the kind of display I’m talking about. Nice to see they’re still around.
The ones I have are all just grids, higher resolution than these but still comfortingly blocky. I’ve actually replaced the dash display recently since the original one got deep fried under the sun and lost all contrast when the weather was above 20°C.
Ah, good to hear it. They do (or did, and I assume still do) also have higher res displays.
Going back to an earlier bit in the conversation, where you were concerned about light sources in the car, I think that auto-dimming might also help (not just with VFDs, but the brightness of any in-car display). My car dash has the option to automatically set brightness based on ambient light levels (something that I wish my desktop computer monitor could do...part of "dark mode"'s benefit is a mitigation for devices that don't do this). I don't know if that was a thing back in the 1980s or so, when these display designs were popular.
I also kind of wonder if eye-tracking, which has come a long way, could be made reliable-enough and responsive-enough to toggle off displays if the car can detect that a user is looking somewhere away from them. Maybe be conservative, not with some critical displays, but stuff like the radio or clock or something. Eye tracking systems normally use the near-infrared, as I understand it, not visible light, so I'd think that you could theoretically do it in a darkened car without problems.
Many receivers and amplifiers still have VFDs to this day. I still wonder why, LCD has to be significantly cheaper.
They look cool as hell though, so I appreciate that they go the extra step.
My kid's car is like this. I've been calling it retro-futuristic, which I think is a pretty apt description.
Oh what kind of car? I’d love for this style to come back for a bit.
Suzuki Aerio SX. I can't find a picture that shows the whole dash, but here's part of it:
