I miss monochrome for programming. I had a 19” portrait monochrome CRT back in the day. Still maybe the best monitor I ever used. Never had a color fringing issue!

You can buy eInk monochrome displays now. You might be interested in them (https://shop.boox.com/products/mira) .

I didn't even mean that. I mean I have a color screen but the pages are usually white background with black text or black background with white text.
