6.10. Assign Color Profile

The Assign Color Profile allows you to assign a new ICC profile to an image.

6.10.1. コマンドの呼び出し方

You can access this command from the image menu bar through Image → Color Management → Assign Color Profile.

6.10.2. Use Notes for Assign Color Profile

When importing an image from disk, sometimes you might want to assign a new ICC profile to the image:

  1. The image might not have an embedded ICC profile, in which case GIMP will automatically assign one of GIMP's built-in sRGB profiles:

    • If the image really is an sRGB image, then no further action is required.

    • If the image is not an sRGB image, then use Assign Color Profile to assign the correct ICC profile from disk.

  2. The image might have an embedded ICC profile, but maybe it's not the right profile for the image, or maybe it's just not the profile you want assigned to the image. Use Assign Color Profile to assign another profile from disk.

  3. The image might have an embedded sRGB profile, but you want to assign a GIMP built-in sRGB profile in place of the embedded sRGB profile. Or conversely, maybe the image is in GIMP's built-in sRGB color space, but you want to assign an sRGB profile from disk.

6.10.3. An example with screenshots showing how to use Assign Color Profile

Let's say you just imported an image file that you know should be in the AdobeRGB1998 color space. But for any number of possible reasons the image doesn't have an embedded ICC profile.

In cases where the image doesn't have an embedded ICC profile, GIMP will automatically assign a built-in sRGB profile. So your AdobeRGB1998 image won't show correct colors until you assign an AdobeRGB1998-compatible ICC profile from disk. The screenshots below show the procedure:

  1. Accessing 「Image/Color Management/Assign Color Profile」 brings up the Assign ICC Color Profile dialog shown below:

  2. Under Current Color Profile is a description of the currently assigned color profile, in this case GIMP's built-in sRGB profile. Clicking on the "+" icon next to the description of the currently assigned profile displays the contents of various information tags in the assigned ICC profile.

    Clicking on the "+" icons next to the words Profile details displays the contents of various information tags in the ICC profile that you pick to be assigned to the image. Until you've actually picked a new profile, the profile in the Assign box defaults to a GIMP built-in sRGB profile.

    The screenshot below shows example profile descriptions revealed by clicking on the "+" icons:

  3. Between Assign and Profile details is a drop-down box that allows you to pick a new profile. Clicking in the drop-down box brings up a list of recently used profiles (if any). At the bottom of the list is an option to Select color profile from disk...:

  4. Clicking on Select color profile from disk... brings up the Select Destination Profile dialog for navigating to the disk location of the profile that you want to select from disk. The box has three panels:

    1. The panel on the left allows you to navigate your on-disk folder structure to the folder of your choice.

    2. The center panel initially shows another list of recently used profiles.

    3. If you click on one of the recently used profiles, the right panel will show informational tags that are embedded in the selected profile.

    If the profile you want to select is shown in the list of recently used profiles, the profile can be directly selected from the list of recently used profiles by clicking on the Open button in the lower right corner. However, as the desired profile isn't in the list of recently used profile, the next step is to navigate to the profile's location on disk.

  5. As shown in the screenshot below, the left and center panels of the Select Destination Profile dialog allow you to navigate to where your ICC profiles are stored on disk, and then pick an appropriate ICC color profile (in this example, an AdobeRGB1998-compatible profile), and the right panel displays informational tags embedded in the selected profile. Click on the Open button to assign the selected profile to your image.

  6. Clicking on the Open button returns you to the Assign ICC Color Profile dialog, allowing you a chance to either assign the selected profile or else pick a new profile. Once you are sure you've picked the right profile, click on the Assign button (lower right corner), and the selected profile will be assigned to the image:

  7. And now the image has been assigned an AdobeRGB1998-compatible ICC profile, and the colors are correctly displayed:
