I left the Mac open while helping Mrs Piper in the kitchen - came back and the colours are all reversed, like an old colour negative. PiperCub must have been tinkering.
Any idea how to get the colours back to normal? I re-started, but it didn’t make a differences.
I think it’s an attempt to increase contrast. White on black seems to have a slightly higher contrast than black on white. Still, I’d agree it’s mostly useless without also changing other colors to make them high contrast.
And no one benefits form seeing an image in negative. Just make it bright.
Ah, that makes sense. I’ve heard before that text is easier to read if it’s white on black; didn’t occur to me when I asked for help, because the app I had open when the Cub worked his magic was full of images.
