I am sure if you are a graphic or web designer,
it happens with you all the time.
You finished a design in PS and ready to convert it to a JPG file for a website and the color of the JPG is totally different
than the PDS file color.
You can get around this issue doing the following:
After I am done with the site in PS.
Edit>Convert to Profile> Find you monitor profile>
Engine: Adobe,
Intent: Perceptual,
uncheck the Flatten Image>
click OK
Go Edit>
Assign Profile>
check Do not color manage this document>
click OK
You will see that the color change on your file.
Now if you Save it for Web, you will get your previous/original color.
Advice: Do it only once and save in Action.
Save a lots of time for you!
Have fun!
