hfy-default-face-def

hfy-default-face-def is a variable defined in `htmlfontify.el'.
Its value is

nil

Documentation:
Fallback `defface' specification for the face 'default, used when
`hfy-display-class' has been set (the normal htmlfontify way of extracting
potentially non-current face information doesn't necessarily work for
'default).

Example: I customize this to:

((t :background "black" :foreground "white" :family "misc-fixed"))

You can customize this variable.
