Ncurses colors
I am using ncurses to develop a user interface. Perhaps I should be using something else, but I am reasonably comfortable with ncurses and don't really want to climb another learning curve at this time.

One problem I have dealt with for many years is ncurses' colors. I have simply been unable to affect the standard colors that are inherent to the code. Specifically, at least a couple of the standard colors look like they have been washed in mud!

COLOR_WHITE, when used as a background, is a light grey. Using a color_pair of COLOR_BLACK, COLOR_WHITE results in dark grey letters on a light grey background.

OTOH, COLOR_WHITE,COLOR_RED has nice bright white letters on a nice red background.

The standard COLOR_YELLOW looks like mustard, not a bright yellow like I would desire.

init_color doesn't seem to have any effect at all.

I have collected sample of what ncurses gives me in the attachment. To illustrate my dislike of the ncurses colors, I have embedded the samples in a background of the same colors as GIMP supplies. The black text labeling each piece was supplied via GIMP.

Suggestions?

set_color

set_color(1)							       fish							      set_color(1)

NAME

       set_color - set_color - set the terminal color

set_color - set the terminal color
   Synopsis
       set_color [-v --version] [-h --help] [-b --background COLOR] [COLOR]

   Description
       Change the foreground and/or background color of the terminal. COLOR is one of black, red, green, brown, yellow, blue, magenta, purple,
       cyan, white and normal.

       o -b, --background Set the background color

       o -c, --print-colors Prints a list of all valid color names

       o -h, --help Display help message and exit

       o -o, --bold Set bold or extra bright mode

       o -u, --underline Set underlined mode

       o -v, --version Display version and exit

       Calling set_color normal will set the terminal color to whatever is the default color of the terminal.

       Some terminals use the --bold escape sequence to switch to a brighter color set. On such terminals, set_color white will result in a grey
       font color, while set_color --bold white will result in a white font color.

       Not all terminal emulators support all these features. This is not a bug in set_color but a missing feature in the terminal emulator.

       set_color uses the terminfo database to look up how to change terminal colors on whatever terminal is in use. Some systems have old and
       incomplete terminfo databases, and may lack color information for terminals that support it. Download and install the latest version of
       ncurses and recompile fish against it in order to fix this issue.
