Why did all my work in photoshop turn to grayscale?

[mightyhumbug]

I have been researching how to fix this problem but the solutions are not working for me. I tried pressing CMD 2 and changing to rgb color via "Image" "Mode" "RGB Color" but neither of those worked. Then I went to my channels and everything is selected with the eyeball. I do not know what to do. Please help.

Could you please post a screenshot with the pertinent Panels (Toolbar, Layers, Channels, Options Bar, History, …) visible? 

Once an image is grayscale changing the Image Mode to RGB will not introduce color or restore color that has been removed previously. 

What kind of image did you actually start with (color mode, bit depth, …), what did you do to it, …? 

Can you step back in the History or snapshots to before whatever happened happened?

The thing is that any image that I introduce to photoshop turns into grayscale even with all of these things checked. I closed my photoshop to try and see if reopening it would help but it didn't. Heres another picture with the layers. I started off with a regular image jpeg I think. It was working fine until I made a new tab to make a youtube banner. All of a sudden everything turned into grayscale. Even the work in my other tabs.

In order of likelihood:

• As c_pfaffenbichler pointed out, it could be visible in your history panel as well right after it happens.
• What I had in the past was that I hit Cmd+Y to get a proof color preview and my proofing color profile was set to grayscale. That would not show up in the history... What happens when you hit Cmd+Y? Does it revert to color or do nothing? You can see whether it's showing proof colors by going to "View"and look for "Proof Colors"
• Ultimately, you could check whether you have any scripts in the ScriptEvent Manager.
  You can go to "File > Scripts > Script Event Manager..." to see if you have any scripts there. Deactivate the checkbox to make sure nothing is running in the background.

»I hit Cmd+Y to get a proof color preview and my proofing color profile was set to grayscale.«

And that would be indicated in the top bar of the image but the original poster decided to clip that off the screenshot, respectively hide it behind the menu.

The Channels Panel seems to show that all three Channels are (about) the same, so I doubt it’s the soft proof. 

The Script Events Manager on the other hand seems like a good suspect. 

But it seems a little specific for someone to set it accidentally or simply forget having set it to desaturate images at opening … if multiple persons have access to the computer, though, who knows what those others may have done?

Please open some colorful image (downloaded from the web or whatever) and post a screenshot that includes the Layers, Channels, History panels. 

And don’t clip the screenshot.
