I really liked the old look, gray case with the black inlet for the screen, I think that was recognisable enough. But I also don't mind their new style. If they want to go with it, why not...

Yeah! it's definitely not more relaxing, in software i think dark themes are a lot better since they don't blast as much light into your eyes, but, they are emissive devices, you can use them with no environmental light, but when it comes to reflective and not emissive surfaces, black/dark letters/numbers/symbols are more easily perceived against a white/light background than the other way around. Our eyes don't work exactly like a camera, but we don't have infinite dynamic range, and can't adjust to brightness changes instantly, so to switch from looking at a white/light surface or an emissive light source like a display then turn to the oscilloscope (which also has an emissive display!) it isn't a smooth transition to easily and clearly see the white writing on black buttons, on a black panel since the eyes now have to adjust to less light going in. It's not super slow or very annoying, but it is noticeable. I feel like going with a dark-ish grey like the color of the ti 89 titanium (maybe also on other ti calculators, i don't know) would have been a better choice if they wanted to dark mode test equipement

I can remember when blue LEDs came out, designers just went nuts with them.

Well, I do think they can look cool.
I don't see the problem with the color, but I feel like 90% of products just completly overdo it with brightness! Maybe efficiency got so much better while many engineers still use LED currents that were adequate 20 years ago?

I don't think black front panel impacts the usability all that much.

It is true that black text on white paper is more readable than white text on black paper. But that is mostly with thin lined fonts, once a more bold looking font is used it doesn't matter so much anymore. Perhaps if anything the colored markings such as yellow green blue pink channel markings stand out even more on a black background. Also there is the benefit that mat black plastic tends to be more forgiving to bumps, scrapes, dirt, aging etc... So in my opinion doesn't really degrade the usability of the instrument. I just prefer the old colors. I especially liked the older HP tan gray fake leather texture case with beige front(but that understandably looks kinda dated these days). For example Tektronix is still sticking to its unmistakable Tek blue color for the scopes. Fluke is sticking to its unmistakable bright yellow on handheld DMMs

Dark mode for software is different. It does genuinely help when working late at night in a dark room. Makes for less contrast between the room and the screen and has less of a tendency to upset your biological clock compared to looking at a bright cool white background of a typical text editor. The human body associates bright cool white light as being mid day. So that makes the dark color theme of all these oscilloscopes perfectly suited for those long late nights of debugging your circuits, since as we all know this is when the best work happens. ;D

EDIT: Regarging blue LEDs. Yes they are usually simply too bright, but would look okay at a normal brightness. I think this is because even the early blue LEDs (They only became widely commercially available around the years of 2000s) had really good efficiency. We do also have really high efficiency green and red LEDs too, but for some reason companies seam to still be producing the old 1990s LED designs that need 10mA to get anything useful out of it and selling it so cheep that people keep using them. While the typical blue LED only needs like 1 or 2 mA to be as bright as you would ever need for a indicator led.

Agree, "too much of a good thing" is a real problem with many blue LED implementations.
