# Search

This window, labelled `Search`, is used to find a system color most closely matching a given one. You can specify a color to match in several ways: by explicitly giving the RGB values using the sliders, by dragging and dropping a color from some other color source, such as default GNOME color selector (if you have selected the option On drop->Search in Settings menu), or by grabbing a color of any pixel on the screen. To use this last method, click on Grab button in the toolbar. Your mouse cursor will turn into a dropper. Place the tip of this dropper over any point of the screen and click. `GNOME Color Browser` will analyze the color of this point, determine the RGB values, and show this color and the RGB values in the `Search` window. It will also show all system colors closely matching this one.

`GNOME Color Browser` shows only those colors which match the given one "close enough", and orders them by how close they are, so that the best matches are shown first. You can adjust its tolerance by using the `Tolerance` slider: smaller values make `GNOME Color Browser` to be more selective, so that only very close matches are shown. Setting the tolerance value to 0 will show only exact matches; setting tolerance to 100 will show all the colors.

By default, `GNOME Color Browser` only looks for matches among the system colors. This can be changed TODO

Another configurable option is the update mode. By default, `GNOME Color Browser` continuously updates matches when you change the color (for example, by using the RGB sliders) —. If you find that this is slow on your system, you can use Settings->Search update to change the update mode to `Discontinuous` (`GNOME Color Browser` will only update matches after you released the slider) or `Delayed` ((`GNOME Color Browser` will update matches with a delay of about 1/2 second).
