To Import a Color Book

In the Color Book Editor dialog, select File > Import.
The Import Color Book dialog opens.
From the list of CSV files, select the color book to import, and click Open.

You can open an exported color book in a text editor or spreadsheet application (such as Microsoft Excel), make changes, save it and import the modified color book file into the Color Book Editor.

In an exported color book (.csv) file, the first line contains column headers. Each subsequent line corresponds to a color in the color book as follows:

<color_name>, <RGB_red_value>, <RGB_green_value>,
<RGB_blue_value>

When importing a color book file, the first line must contain the column headers as shown above: Color, R-255, G-255, and B-255.
