When I open an image in Photoshop, it appears to be washed out and displays incorrect colors. I am using Windows.
Image displayed in Photoshop:
Open Color Management in Windows (search for it using the Start menu). It should look like this:
Check the box titled Use my settings for this device.
Select sRGB IEC-61966-2.1 and hit OK.
With this profile selected, click Set as Default Profile.
It should now say (default) after the profile name.
You're done. Close the window and reopen Photoshop. Your image should now show the proper colors.
