This article explains how to change the theme color of the FortiGate GUI or SSL-VPN Portal for Web Mode, and how to list the available colors.
Solution
FortiGate GUI Theme:
- v7.2.X. From GUI: Go to System -> Settings -> View Settings -> Theme and select the drop-down menu to see the list of theme colors.
From CLI: As this is a global change, the command needs to be run in the global mode:
config system global
set gui-theme ? <----- Here, the question mark provides the list of available themes for GUI.
jade <----- Jade theme (green color).
neutrino <----- Neutrino theme (dark blue color).

dark-matter <----- Dark-matter theme (dark theme with purple color).
onyx <----- Onyx theme (dark theme with green color).

set gui-theme jade
end
The theme for the GUI has been changed to the green (jade) color theme.
