5 After choosing the settings you want, click OK. If you select the Custom option, the Color Table dialog box appears. To use this dialog box, see “Creating custom color tables for Indexed images,” page 31.625. Creating custom color tables for Indexed images You can create a custom color table for an Indexed image in two ways. 1 Select “Custom” in the Indexed Color dialog box (see “Indexed image mode,” page 31.623). Click OK in the dialog box and Canvas opens the Color Table dialog box. 2 With an Indexed image selected, choose Image > Mode > Color Table. In the Color Table dialog box, you can edit individual colors in the palette, create a blend of colors, and select from several preset color palettes, including System and Grayscale palettes. You can also save a palette file, or load a palette file. In the Color Table dialog box, a grid of 256 color swatches appears; each swatch represents one color in the palette. By default, the Cus- tom option appears in the Table pop-up menu, and the color swatches show the last palette used in the dialog box.
