### 7.5.25 Display/Color Filter

Color Filter controls the visibility of a layer on a per pixel base.

With Layer you can define which color values a layer pixel must have in order to be visible, and with Background you define which color values a background pixel must have, so that the corresponding layer pixel is visible.

There are 3 possible color modes to lay down the visible color ranges:

- the color mode of the given picture
With Layer this is the color mode of the layer and with Background the color mode of the document. If the color mode has more than one channels, every channel can be used for setting the color range.
- Gray
There is a single channel, that corresponds to the brightness of the pixels.
- HIS
There are the channels hue, intensity and saturation

If you apply Fix Layer (see chapter 7.5.24) to a layer with a color filter, the color filter will be converted to a layer mask (see chapter 2.8).
