Sets the fg and bg color. May be called as often as you like, since

if the new color is the same as the previous, nothing will be
|
|
written. Negative values for set_color will also be ignored. Since
|
|
the terminfo string this function emits can potentially cause the
|
|
screen to flicker, the function takes care to write as little as
|
|
possible.
|
|
|
|
Possible values for color are any form the FISH_COLOR_* enum,
|
|
FISH_COLOR_IGNORE and FISH_COLOR_RESET. FISH_COLOR_IGNORE will
|
|
leave the color unchanged, and FISH_COLOR_RESET will perform an
|
|
exit_attribute_mode, even if set_color thinks it is already in
|
|
FISH_COLOR_NORMAL mode.
|
|
|
|
In order to set the color to normal, three terminfo strings may
|
|
have to be written.
|
|
|
|
- First a string to set the color, such as set_a_foreground. This
|
|
is needed because otherwise the previous strings colors might be
|
|
removed as well.
|
|
|
|
- After that we write the exit_attribute_mode string to reset all
|
|
color attributes.
|
|
|
|
- Lastly we may need to write set_a_background or set_a_foreground
|
|
to set the other half of the color pair to what it should be.

|
|
|
\param c Foreground color.

\param c2 Background color.
