iMac monitor displaying two different colors instead of one when solid colors are used on websites.
I took a screenshot of what I'm experiencing when visiting websites with background colors for their content modules. I see two different colors displayed. The actual color of the website pictured in the screenshot is the darker red but the display shows a brighter color as well and there is a clear deliniation. This happens across the board with all colors and not just red. I was wondering what is causing this issue and can it be fixed by me or do I need to have the iMac checked by Apple?
