How to handle text if no text colour has been explicitly specified by the user.

contrast

(default) automatically select a contrasting colour for enhanced readability.

asis

render text in the default text colour for the output device, unless the user has already specified a text colour at this location

remove

remove all text without a user-defined colour

text_contrast

When text_mode='contrast' this numeric value in range [0, 1] adjusts the visibility. Default: 1 (high contrast)

Value
