## 12. 팔레트

A palette is a set of discrete colors. In GIMP, palettes are used mainly for two purposes:

- 한정된 수의 튜브만을 가지고 유성 그림을 그리듯 팔레트 내의 색상으로만 칠을 할 수 있습니다.

- They form the colormaps of indexed images. An indexed image can use a maximum of 256 different colors, but these can be any colors. The colormap of an indexed image is called an "indexed palette" in GIMP.

Actually neither of these functions fall very much into the mainstream of GIMP usage: it is possible to do rather sophisticated things in GIMP without ever dealing with palettes. Still, they are something that an advanced user should understand, and even a less advanced user may need to think about them in some situations, as for example when working with GIF files.

When you install GIMP, it comes supplied with several dozen predefined palettes, and you can also create new ones. Some of the predefined palettes are commonly useful, such as the “Web” palette, which contains the set of colors considered “web safe”; many of the palettes seem to have been chosen more or less whimsically. You can access all of the available palettes using the Palettes dialog. This is also the starting point if you want to create a new palette.

Double-clicking on a palette in the Palettes dialog brings up the Palette Editor, showing the colors from the palette you clicked on. You can use this to paint with the palette: clicking on a color sets GIMP's foreground to that color, as shown in the Color Area of the Toolbox. Holding down the Ctrl key while clicking, on the other hand, sets GIMP's background color to the color you click on.

You can also, as the name implies, use the Palette Editor to change the colors in a palette, so long as it is a palette that you have created yourself. You cannot edit the palettes that are supplied with GIMP; however you can duplicate them and then edit the copies.

When you create palettes using the Palette Editor, they are automatically saved as soon as you exit GIMP, in the `palettes` folder of your personal GIMP directory. Any palette files in this directory, or in the system `palettes` directory created when GIMP is installed, are automatically loaded and shown in the Palettes dialog the next time you start GIMP. You can also add other folders to the palette search path using the Palette Folders page of the Preferences dialog.

GIMP palettes are stored using a special file format, in files with the extension `.gpl`. It is a very simple format, and they are ASCII files, so if you happen to obtain palettes from another source, and would like to use them in GIMP, it probably won't be very hard to convert them: just take a look at any `.gpl` and you will see what to do.

### 12.1. 색상표

Confusingly, GIMP makes use of two types of palettes. The more noticeable are the type shown in the Palettes dialog: palettes that exist independently of any image. The second type, indexed palettes, form the colormaps of indexed images. Each indexed image has its own private indexed palette, defining the set of colors available in the image: the maximum number of colors allowed in an indexed palette is 256. These palettes are called “indexed” because each color is associated with an index number. (Actually, the colors in ordinary palettes are numbered as well, but the numbers have no functional significance.)

The colormap of an indexed image is shown in the Indexed Palette dialog, which should not be confused with the Palettes dialog. The Palettes dialog shows a list of all of the palettes available; the Colormap dialog shows the colormap of the currently active image, if it is an indexed image – otherwise it shows nothing.

You can, however, create an ordinary palette from the colors in an indexed image—actually from the colors in any image. To do this, choose Import Palette from the right-click popup menu in the Palettes dialog: this pops up a dialog that gives you several options, including the option to import the palette from an image. (You can also import any of GIMP's gradients as a palette.) This possibility becomes important if you want to create a set of indexed images that all use the same set of colors.

이미지를 인덱스 모드로 바꿀때, 가장 주된 작업은 이미지에 대한 인덱스 색상표를 만드는 것입니다. 이에 대한 자세한 설명은 Section 9.6, " The Indexed mode" 에 있습니다. 이에 대해 간단히 말하면, 팔레트 대화 상자에 있는 특정 팔레트를 이용하는 방법에 관한 것입니다.

정리하자면, 일반적인 팔레트는 이미지를 인덱스 모드로 바꿀때 인덱스 색상표로 바뀌게 되며, 인덱스 색상표는 팔레트 대화 상자에서 가져오기를 통해 일반적인 팔레트로 만들 수 있습니다.
