LightDarkSwitched¶

Represents an expression that switches between a light-mode and a dark-mode variant depending on the current appearance.

LightDarkSwitched[light, dark] uses light in light mode and dark in dark mode. With a single argument (or Automatic), the missing variant is derived automatically. The kernel does not resolve the switch — it stays symbolic and is resolved by the front end when rendering:

$ wo 'LightDarkSwitched[Red, Blue]'
LightDarkSwitched[RGBColor[1, 0, 0], RGBColor[0, 0, 1]]

$ wo 'LightDarkSwitched[Red]'
LightDarkSwitched[RGBColor[1, 0, 0]]

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

$ wo 'ColorQ[LightDarkSwitched[Red, Blue]]'
False
