Thanks for bringing this up, Charles 🙂 I used to own/run a web design/dev company for 10+ years, up until a few years ago, and we started to pay attention to compassionate design principles like this.
Also, I’m part way to your experience with regards to my eyes 😛 I have to blow up fonts on most websites, which is easy to do, but the contrast thing might be slowly creeping in as I’ve often wondered why I don’t like ‘dark mode’ so much. Guessing low-contrast sensitivity is it.
Yes, there are accessibility settings, which I definitely use on my iPhone, like increasing font size and contrast, but settings beyond that really mess with a lot of aesthetics. Desktop has more variables I’ve found too. And the important note here is that a color scheme can be picked that pleases everyone 🙂
I see this forum is running BBPress, on a WordPress install, and I see that there is a plugin out there that offers a dark mode switch for folks. If that works, this is a way to give folks an option to go dark if they prefer (Droit Dark). But really, different color palette would be easiest.
