A janela

A caixa de diálogo Escolher cor possui quatro áreas principais.

- Os botões de opção selecionam o componente da cor. Este componente pode se expresso tanto nos modelos RGB (vermelho, verde e azul) ou HSB (matiz, saturação e brilho). O modelo CMYK não é selecionável e é fornecido para facilitar a entrada de valores de cor com notação CMYK.

Click in the big color area on the left to select a new color. Using this selector area you can modify two components of the color as represented in the RGB or HSB color models. Note that these are the two components not selected with the radio buttons on the right side of the dialog.

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.
