I’ve been working a lot with color profiles and trying to get my photos to look the same in different browsers lately (photos look very different in Firefox vs Safari). This has made me more aware of color profiles and display temperatures than usual so I thought I was just seeing things when I returned to my laptop from getting coffee, flicked my mouse to turn off the screen saver and noticed that my screen looked a bit off. Turns out it was. Somehow during the screensaver the profile changed from Color LCD to Adobe RGB. I only noticed this by opening up the display preferences panel. Upon opening the panel the profile changed (automatically) back to color LCD.
