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.
