### 7.6.11 Color/Set Color Profile

PhotoLine can assign a ICC color profile (see chapter 2.11) to layers, pages and a whole documents. On displaying a layer on the screen the color profiles will be used according to the following rules:

- If the layer has an own profile, this one will be used.
- If the layer has no profile, the profile of the next group will be used which the layer is embedded in.
- If no group has a profile, the profile of the page will be used.
- If no page has a profile, the profile of the document will be used.

If your document is a picture (see chapter 2.10) the background layer cannot have a color profile on its own. Instead the profile will be assigned to the whole document. In the Attributes-dialog (see chapter 4.8) you can inspect, whether a color profile is assigned to a layer, a page or a document. Here you can delete the color profile, too, so you don‘t have to always use Set Color Profile.

By assigning a color profile the data of a image layer isn‘t changed, but they will be interpreted differently on displaying. Therefore assigning a color profile can change the appearance of a layer significantly.

In addition to the effects above assigning a color profile to a document or page has one more important meaning. By assigning a color profile the working color space of a document/page is changed. Without color profile documents are working in RGB-mode. But after assigning a profile (i.e. a gray profile or a CMYK profile), the color space of the profile will be the color space of the document. This will influence many parts of PhotoLine:

- Adjustment layers offer the channels of the working color space for editing.
- The channel palette uses the working color space.
- If a document or a part of a document has to be rendered as image, this image will be created using the working color space. This affects normal working as well as saving.
