EAS Colour Settings
There are three different levels of EAS messages – warning messages, watch messages and test
messages. Each message typically has a different background and foreground colour associated with
it so that the viewer will immediately know the severity of the EAS alert.
In order to change colour settings for the background and foreground parameters, select the colour
palette on the right of the EAS screen and the “Choose a Colour ” dialog box will appear. In this dialog
box the user can select a colour using Swatches, HSB, and RGB formats.
