Sorting the color table
You can sort colors in the color table by hue,
luminance, or popularity, making it easier to see
an image's color range and locate particular colors.
To sort a color table:
Choose a sorting order from the Color Table
palette menu:
Unsorted. Restores the original sorting order.
•
Sort By Hue, or by the location of the color on
•
the standard color wheel (expressed as a degree
between 0 to 360). Neutral colors are assigned a
hue of 0, and located with the reds.
Sort By Luminance, or by the lightness or
•
brightness of a color.
Sort By Popularity, or by the colors' frequency of
•
occurrence in the image.

You can add colors that were left out in building
the color table. Adding a color to a dynamic table

color. Adding a color to a fixed or Custom table
adds an additional color to the palette.
