Hi Ruth,
You can add colors to the color palette (on the bottom of the EasySIGN page) by selecting the option “Edit color-table” as available in the “Fill color” menu within the EasySIGN Toolbox (on the left side of the EasySIGN worksheet). The next step is to select the required color table, in the case the “Avery 700 series” and select all available colors (Shift + left mouse button) to add all colors to your color palette.
Have an easy day!
Wilbert at EasySIGN
