Since it was a few days after, I think your display color issues are unrelated to the browser update.
Might someone have changed the style selections for windows? There are many preset color schemes, changed with a click of a button.
Other possibilities would be hardware or firmware, like the display itself, graphics card/chip, or graphics drivers.
Laptop computer? Colors and brightness start going weird with partial failure of the connection (usually ribbon cable) between base and display. I had one go like this, for a few months could restore normality with a tap on the side of the display, but eventually retired the machine. Was a good excuse for processor, memory, storage and OS upgrades I wanted anyway.
