I need help to make a userscript to target all white background and turn them black and all black text to silver using javascript for all websites, all other elements should stay original. The color range for background is from silver to black and dark gray to black for text. Turn background within those color range to black and text within those color range to silver. This helps reduce eyes strain at night or in a dark room.
I pasted the code section here but caot submit the post so I deleted it.
Please make the code smart enough to detect background color(silver to white) and text color(dark gray to black) and reverse their color. It is not possible with CSS but it works on javascript. Please help with the full javascript code.
Thank You
