iconFg
From SAP Enable Now Wiki
Scope
SAP Companion parameter, specified either in the URL or in the SAP Companion parameters in the linked application.
Purpose
Can be used to set the foreground color of Hotspot icons.
This color used to be applied to all 'info' icons. It will not change 'warning' icons, which will always be shown in yellow (and there is no comparable parameter to change that).
Usage
Specified as:
iconFg={RR,GG,BB}
where {RR,GG,BB} are the comma-separated decimal RGB values of the required color (so “255,0,0” for red). (You can specify them as hex values [e.g. #FF0000] in the application – but obviously using a # wouldn’t work in a URL.)
