Revert colours that have become dull, washed out and desaturated suddenly in Illustrator

[jhannel]

I was working on a .ai file. I had created a group of graphics and was working on another one zoomed in. I saved the file when I was done. When I zoomed out I saw that all the colours of the other graphics had changed by themselves and now looked so washed out and desaturated. My question is, is there a way to revert my colours back to what they looked liked previously. The copy I am working on is the only copy I have as I've saved over previous version.

And you don't use Time Machine or the like?

And you have already closed the file?

And a computer restart also didn't help? Sometimes these things just get hung up.

In that case: no.

What exactly did you do to that file? How did you save it?

[jhannel]

I don't use Time Machine. 

The file is stll open but even undoing doesn't get it back to normal.

I didn't restart because I didn't want to close the file. 

I just saves its normally pressing save like I had done four other times for that same file.

Did the color values change or just the view on screen?

[jhannel]

The colour values had changed.

Please show your color management settings.

Please tell us how you saved the artwork and how you re-opened it.

Is there a difference between the document color profiles of the before and after documents that you showed?

You can check that at the bottom of your window.

[jhannel]

No there is no difference in colour profiles as this document was created in RGB and was never changed. The colour profile now still matches the colour profile I began with. The first image is of a jpeg image file that I created/saved from the AI document before the colours had changed. The right side is showing the graphics as they currently are in the open AI document. I took a screenshot of the two side by side after I placed the jpeg image into the AI document to compare.

In addition to your Color Management Settings that Monika asked for, can you show your Document Color Profile?
