 **Note:** This filter changes colors linearly, which may lead to losses in the upper and lower color ranges.  Instead you may want to try the Exposure Correction tool which utilizes a more advanced algorithm preventing this undesired effect.

 ==== Color ====
-{{:image_archive:filter:color.png?nolink }} The “Color” tool is used for tinting or adding overall color to an image.  It can be used to colorize grey images for example.  However, the correction of color problems in images is best done with the tools “Color Tuning” or “Hue, Saturation, Brightness.”

 ==== Text ====

-The upper section of the panel defines the text to be displayed.  The default insert text is the system descriptor “Copyright.”   The descriptor name is always bracketed with paired percentage (%) signs to look like this:  **<nowiki>%%descriptor%%</nowiki>**.  Descriptor values can be typed manually and bracketed so.  You can also click the “Insert” button and open the Insert Descriptor window which lets you conveniently choose from a list of available descriptors.  Of course, you will have to make certain that the “Copyright” field or any other descriptor field actually contains text.  Alternatively, you can simply type over the default descriptor with regular text input.  For multi-line text, type “\n” to force a line break.  Right-clicking in the Text field opens a contact menu via which you could alternatively access the Insert Descriptor window as well as the option to insert special characters

-The middle section of the Text panel defines the font, style, shading, and shadow color.  Using the shadow effect is recommended for better readability when text is superimposed on an area with light and dark background.  The shadow color should be a strong contrast to the font color, for example use a black shadow for a white text color or vice versa.

 Further down you’ll find a slider.  With it you can seamlessly adjust the transparency of your text in the image.  Making copyright text somewhat transparent on, let’s say an art photograph, causes less visual disturbance, yet still remains readable.  Large text or a logo sprawled across the entire image in a watermark fashion discourages unauthorized “nabbing” of images from your web site, yet still permits a view of the image itself.

-This tool inverts the transparency of an image.  Opaque areas become transparent and previously transparent areas become colored.  This tool produces many interesting effects and is fun to experiment with.
