Oversaturation on facebook on other devices

@Miss_Val22 

The problem isn't your screen, but whether the application performs color management when sending data to the screen. It's not the hardware, it's the software.

Some applications don't support color management at all, they will never display correctly under any circumstances.

What is certain, is that Photoshop is not the problem. That's why you shouldn't change anything in Photoshop.

The point is that if you see sRGB oversaturated, the color management chain isn't operating - whether it's because the application doesn't support it, or there's a defective component like an icc profile. If the latter, it's usually the monitor profile.

It's almost certainly a color management issue of some kind, but that's an entire can of worms. The problem could be occurring at the photoshop level, like due to the chosen working color space or exported/embedded color space, or it could be at the windows level with a weird ICC profile set, it could be the monitor (though if you didn't change monitors probably unlikely), or it could even be a change in how the facebook app assumes color spaces on photos. Though the fact that you mention it happens on multiple other devices that says to me there is a mismatch of chosen color space somehow on the device you're editing the pictures.

If you want the simplest potential solution, take a look at these two options in the Export As menu when you go to save a photo:

If they are checked, try unchecking them, and vice-versa, etc. You can also try just checking to Convert to sRGB without embedding the color profile.

Another thing you could check is for this setting in Windows to "Automatically manage color for apps". If it's enabled, you can try disabling it, and vice-versa.

I have an entire video about the topic which should be a pretty good primer, it's pretty long but you should have a better idea of why it's happening if you can sit through it. Ignore the semi-clickbait title, you don't necessarily need to change ICC profiles for your monitor, but you'll still have a better understanding of why different devices look oversaturated.
