SystemColor¶

Represents a named color provided by the windowing system theme, such as "Window", "WindowText", or "Highlight".

The kernel does not resolve system colors — they stay symbolic and are resolved by the front end when rendering:

$ wo 'SystemColor["Window"]'
SystemColor[Window]

$ wo 'Head[SystemColor["Highlight"]]'
SystemColor

Since the kernel keeps it symbolic, it is not a color object:

$ wo 'ColorQ[SystemColor["Window"]]'
False
