## The Pick a Color Window

The GTK and Qt variants of LibreOffice on Linux use native system/toolkit dialogs (which are also used by other applications) by default to pick a color instead of the custom dialog that is described in more detail below. Use of the custom LibreOffice dialog instead of the native one can be enabled in the LibreOffice options.

The Pick a Color dialog consists of four main areas.

- The radio buttons select the color component of the color. This color component can be expressed in either RGB (Red, Green, Blue) or HSB (Hue, Saturation, Brightness) color models. The CMYK color model is not selectable and is provided only to ease the input of color values using CMYK notation.

- The spin buttons are for entering the numerical value of the color component.

- With the vertical color component slider you can modify the value of each component of the color. With the large colored square you can select the color component approximately.

- The horizontal bottom color bar shows the current color and the new color, side by side.

Prema na área colorida grande da esquerda para seleccionar unha cor nova. Mediante este selector pode modificar dous compoñentes da cor tal e como se representan nos modelos de cor RGB e HSB. Teña en conta que estes son os compoñentes non seleccionados cos botóns de radio da parte dereita da caixa de diálogo.

In the right part of the bottom bar, you will see the original color from the parent tab, Colors.

In the left part of the bottom bar, the current result of your work in this dialog is visible.

LibreOffice só utiliza o modelo RGB para imprimir a cor. Os controis CMYK son fornecidos só para facilitar a entrada de valores de cor utilizando a anotación CMYK.
