Hello!
If you are working in Photoshop or just starting to master it,
you might encounter an embedded profile mismatch issue.
This means that when you open any photo, Photoshop displays a message with the text
"Document (photo_name) has a color profile that does not match the current RGB workspace"
says that the built-in profile is sRGB IEC61966-2.1, and the working profile is Adobe RGB (1998).
And offers to choose a processing method from three options:
Use the built-in profile (instead of the working one)
Convert Document Colors to Workspace
Do not use embedded profile (do not manage color)
Now we will solve this issue and at the same time find out
what kind of color profiles and which one is better to use in what cases.
Well, let's deal with the profiles first ...
Which color profile should you choose?
sRGB IEC61966-2.1 or Adobe RGB (1998)?
The color space or color profile defines the number of colors
which we can see on the monitor.
In the names of both profiles, the word RGB is common,
that is, it is based on the RGB (Red, Green, Blue) color model.
When mixing these three colors (red - red, green - green, blue - blue)
all other colors and shades are formed. sRGB IEC61966-2.1 color model
was created with the aim of displaying the same image on different monitors various manufacturers(sRGB - standard RGB). And with this task she copes well. Also, the sRGB space is used everywhere on the Internet. And the Adobe RGB model supports a wider palette of colors than sRGB, but the fullness of the photo can only be appreciated on professional monitors, a regular monitor simply cannot display the full gamut depth available in a photo with an Adobe RGB profile. Which profile to choose and how to fix the mismatch error? So, if: you have the most ordinary monitor that you bought at a regular computer store for cheap; you plan to post photos and pictures after processing on the Internet on a blog or simply store them on a computer; and you are not going to print photos on a printer, then choose the sRGB IEC 61966-2.1 color space. Let's see where all this is set up in Photoshop. Open the program, go to the Edit menu and select Color settings ... Or you can press the key combination Ctrl + Shift + K, as seen in the screenshot:
I had some Japan Color for newspapers by default.
It's strange, I don't seem to have relatives in Japan,
why such settings, if I live in Russia - I don’t know :)
Let's correct this misunderstanding. 
I selected in the Web/Internet settings for North America.
Its settings are suitable for my purposes.
Also make sure the checkboxes are checked
‘Ask when opening’ when profiles don't match.
Suddenly, someday you come across a photo with a different color profile,
and you don't even know about it
because in the color management strategy, the RGB parameter is set to
‘Convert to RGB workspace’.
OK it's all over Now.
Press OK
keep these settings and the warnings will no longer bother you.
1. No built-in profile. If, when opening documents, you get a pop-up window Missing an embedded profile:
If you need to turn it off, then execute the command: Editing > Color Adjustment (Shift + Ctrl + K). And remove the checkboxes in front of the items: Ask when opening.
2. Do not open documents in tabs. If, when opening documents in the program Adobe Photoshop CS5, they are added as bookmarks in the panel:
Then, to disable this function, execute the command: Editing> Preferences> Interface... and in the Panels and documents section, uncheck the box before the item: Open documents in tabs.
3. Resizing the thumbnail. To resize the thumbnail, for example in the Layers palette, click right button mouse and select the item from the list: Large thumbnails.
Let's look at the result:
4. Regulatory layers. We call the panel: Correction and click on the button: Brightness / Contrast.
Adjust: Brightness and contrast. To return to the main panel: Correction, click on the left arrow.
Let's look at the result:
5. Working with selection. Select the Oval Marquee Tool (M). To select a circle, hold Shift key.
Hold down the Shift key and select the second circle, and together where the circles intersect, the selection will merge.
Hold down Shift+Alt to select the second circle, and together where the circles intersect, that area will remain the only selection.
Hold down the Alt key and select the second circle, and together where the circles intersect, the selection will be clipped.
One of the most frequently asked questions I hear from students and novice Photoshop users is what to do when a missing or mismatched color profile warning dialog box is displayed. (fig. 1.23). If you do not know what to choose in this case, it is quite difficult to make a decision. In addition, these windows use terminology that differs from that used in the options group. Color Management Policies Color settings(Setting colors). To avoid misunderstandings, try to follow the guidelines below.

Embedded Profile Mismatch Dialog Box
Troubleshooting profile mismatch issues is easy because Photoshop detects the profile assigned to the image and can therefore convert the images to the current RGB workspace. Among the three available options, only the first two are of interest.
Switch Use the Embedded Profile(Use embedded profile) allows you to use an embedded profile, which means that editing the image is carried out in its "native" space, which is temporarily set as the working one. This switch is completely analogous to the parameter Preserve Embedded Profiles(Keep embedded profiles) in the options group Color Management Policies(Color Management Strategies) Dialog Box Color settings(Setting colors).
Switch Convert Documents Colors to the Working Space(Convert Document Colors to Workspace) is probably the most logical choice for most digital camera owners (assuming the profile is valid in this case, of course). When opening an image taken with a digital camera, the sRGB color profile is usually embedded. Because editing images using the Adobe RGB (1998) color space is preferable to using sRGB, converting document colors to workspace makes sense. As a result of the transformation, appearance image, so although the color values change, the image looks exactly the same as when using the embedded profile. This switch is completely analogous to the parameter Convert to Working RGB(Convert to RGB workspace) in the options group Color Management Policies(Color Management Strategies) Dialog Box Color settings(Setting colors).
The last switch Discard the Embedded Profile (Don't Color Manage)(Do not use the built-in profile (do not manage color)), should not be selected. This switch is completely analogous to the parameter Off(Do not apply) in the parameter group Color Management Policies(Color Management Strategies) Dialog Box Color settings(Setting colors). The profile is removed from the image and the colors are interpreted according to the workspace, which is the equivalent of Photoshop choosing the best values for itself. The only case where it makes sense to use this option, - if necessary, remove the bad color profile.
When you open an image without an embedded Photoshop profile, there's simply nothing to "start off" from. In the dialog box Missing Profile(No Embedded Profile) you must specify a method for interpreting the color codes in the file. If you only open files taken with a digital camera, you can choose the best option with a little experimentation. Most modern digital cameras produce images that look their best when using the sRGB working space. If your camera supports the Adobe RGB (1998) workspace, always select it; otherwise, convert images to the given workspace
stvu. Details of the options available in the dialog box Missing Profile(No built-in profile) (Fig. 1.24), described below.

Missing Profile Dialog Box
Switch (Leave unchanged (do not manage color)) is like a radio button Discard the Embedded Profile (Don't Color Manage)(Do not use the built-in profile (do not manage color)) dialog box Embed Profile Mismatch(Embedded profile mismatch), except that in this case nothing is removed from the file due to the lack of the original profile. Photoshop opens the image, interprets the colors in accordance with the current workspace, regardless of whether such a conversion is correct or not.
Switch Assign Working RGB(Assign RGB Working Space Profile) performs the same function as the previous one, except that the current RGB working space profile is applied to the image. Since no numeric values are changed and the image is displayed based on the specification of the current workspace, the image looks exactly the same as when the radio button is selected. Leave As Is (Don't Color Manage)(Leave unchanged (do not manage color)). This radio button should only be selected if you are sure that the image matches the current workspace.
Switch Assign Profile(Assign Profile) allows you to select a specific profile, and then convert the image to a workspace profile after assigning the specified profile. This is very useful if, for example, you know that the sRGB color profile is suitable for images taken with a digital camera, but they still open without a profile. In this case, you need to select the sRGB profile from the drop-down list, and then check the box Convert to Working RGB(and convert to working
space). Having an sRGB profile gives Photoshop enough information to properly convert the image into the workspace. In this case, the only thing missing is preview to be able to evaluate the impact of the profile on the image. However, since the image is not yet open at this stage, there is no need for the preview function.

When opening tutorial images, you need to
select switch Use the Embedded Profile(Use Embedded Profile) to ensure they are color correct.
Books color companion Tim Gray and Real World Adobe Photoshop CS2 David Blatner and Bruce Fraser are great tutorials on learning and fine-tuning working with color in Photoshop.

When I open my raw files in Adobe Photoshop, a window pops up with the message:
The document has an embedded color profile that does not match the current RGB working space.
Built-in: Adobe RGB (1998)
Operation: RGB Monitor - sRGB IEC61966-2.1
What would you like to do?
- Use the built-in profile (instaed workspace)
- Convert document colors to workspace
- Cancel Embedded Profile (Do Not Manage Color)
What does each option mean exactly or what should I choose to best use for editing and final printing?
How can I set the defaults so that it doesn't prompt for such a message every time I open a raw image.

When you open a raw file in PS, it first appears in ACR. There you can set the color space you want to assign to the demuse image. Adobe RGB is a good default, you might want to consider changing it to ProPhoto if you're running in 16-bit mode on PS. You can also select sRGB.
SRGB is the smallest of the three, followed by Adobe and ProPhoto. Working in a wider color space means you have more extreme colors. But for the final output, you may need to convert it as most output devices can't handle those wide spaces! For web use, sRGB is generally still recommended as a common denominator.
When you then continue with PS where your workspace is obviously set to sRGB, you can either
Convert the image to workspace.
This would be a suboptimal solution. If you want to limit your image to sRGB while editing, do it already in ACR as mentioned earlier.
Use built-in space.
This effectively means to ignore the default PS and switch the workspace to Adobe RGB for that image.
Discard (ignore) the built-in profile.
This is the worst and probably the wrong option. Your image will be displayed with wrong colors, not at all like you, painstakingly completing it in ACR!
So, in summary, work in the same color space you created from ACR, and consider the end space when saving, e.g. JPEG.
For printing, the last step is usually a soft check, where you show the image converted to your printer's color profile and tweak it to look its best under its limitations.

Thanks for your reply. I have 2 options in my nikon camera: sRGB (current) and Adobe-RGB. Could you briefly explain which option should be used in photoshop (and/or ACR) to get best results when printing? I want to set the default values so that it doesn't prompt for such a message every time I open a raw image.
S.Serp
I see some options in the Edit > Color Settings menu, what should be set for the RGB, CMYK, ... dropdown menus?
What you have installed in the camera has nothing to do with raw. Set acr and ps to the same rgb profile. sRGB is the easiest, but Adobe RGB may be better if your output device can support mire than srgb. but that's up to you. cmyk doesn't matter.

This is "true", but the view misses the point. You never must set the workspace to your monitor profile, you must set it to workspace... in this case it will be Adobe 98. Do any profile recalculation once and once only when exporting, saving original file always to the original profile. Your monitor profile is always automatically taken into account in the display, you never want it in your workflow.

@Tetsujin I want to set defaults so that it doesn't prompt for such a message every time I open a raw image. So: 1) should I choose sRG or AdobeRGB in my camera, 2) What should I set in photoshop's Edit > Color Setings > RGB option? 3) in the ACR plugin when I open a raw file (I don't know where its options are, but there is a link at the bottom of the screen that talks about a color profile and seems to remember the selection for the next file)
