## 9. Colors dialog

The Channel dialog lets you manage and pick up new colors. It is divided into five seperate parts: GIMP, CMYK, Triangle, Watercolor and Scales. You can use the eyedropper, which is the last button of the dialog, to pick up a color anywhere on you screen.

### Overview

Introduction

### Activate Dialog

The dialog can be called in the following ways :

- from the toolbox-menu: File->Dialogs->Colors

- from the toolbox: click on the current Foreground or Background color.

- from the image-menu: Dialogs->Colors

- from an other dialog-menu: Add Tab->Colors

### The GIMP Selector

With the GIMP Color Selector, you select a color by clicking on a one-dimensional strip located at the right edge, and then in a two-dimensional area located on the left. The one-dimensional strip can encode any of the color parameters H, S, V, R, G, or B, as determined by which of the adjoining buttons is pressed. The two-dimensional area then encodes the two complementary color parameters.

### CMYK

The CMYK view gives you the possibility to manage colors from the CMYK color model.

### Triangle

The Triangle selector is made up of a chromatic circle that allows to select Hue by click-and-drag a small circle and of a triangle that has also a small circle to vary intuitively Saturation and Value.

### Watercolor

### Scales

### Color picker

The color picker has a completly different behaviour, than the color picker tool. Instead of picking the colors from the active image, you're able to pick colors from the entire screen.
