- Most color terminals are either "Tektronix-like" or "HP-
- like". Tektronix-like terminals have a predefined set of
- N colors (where N usually 8), and can set character-cell
- foreground and background characters independently, mixing
- them into N * N color-pairs. On HP-like terminals, the
- use must set each color pair up separately (foreground and
- background are not independently settable). Up to M
- color-pairs may be set up from 2*M different colors.
- ANSI-compatible terminals are Tektronix-like.
+ The curses library functions <STRONG>init_pair</STRONG> and <STRONG>init_color</STRONG>
+ manipulate the <EM>color</EM> <EM>pairs</EM> and <EM>color</EM> <EM>values</EM> discussed in
+ this section (see <STRONG><A HREF="curs_color.3x.html">curs_color(3x)</A></STRONG> for details on these and

Some basic color capabilities are independent of the color
method. The numeric capabilities <STRONG>colors</STRONG> and <STRONG>pairs</STRONG> specify
- the maximum numbers of colors and color-pairs that can be
- displayed simultaneously. The <STRONG>op</STRONG> (original pair) string
- resets foreground and background colors to their default
- values for the terminal. The <STRONG>oc</STRONG> string resets all colors
- or color-pairs to their default values for the terminal.

- To change the current foreground or background color on a
- Tektronix-type terminal, use <STRONG>setaf</STRONG> (set ANSI foreground)
- and <STRONG>setab</STRONG> (set ANSI background) or <STRONG>setf</STRONG> (set foreground)
- and <STRONG>setb</STRONG> (set background). These take one parameter, the
- color number. The SVr4 documentation describes only
- <STRONG>setaf</STRONG>/<STRONG>setab</STRONG>; the XPG4 draft says that "If the terminal
- supports ANSI escape sequences to set background and fore-
- ground, they should be coded as <STRONG>setaf</STRONG> and <STRONG>setab</STRONG>, respec-
- tively. If the terminal supports other escape sequences
- to set background and foreground, they should be coded as
- <STRONG>setf</STRONG> and <STRONG>setb</STRONG>, respectively. The <STRONG>vidputs</STRONG> function and the
- refresh functions use <STRONG>setaf</STRONG> and <STRONG>setab</STRONG> if they are
- defined."
+ While the curses library works with <EM>color</EM> <EM>pairs</EM> (reflect-

+ if they are defined.
The <STRONG>setaf</STRONG>/<STRONG>setab</STRONG> and <STRONG>setf</STRONG>/<STRONG>setb</STRONG> capabilities take a single
numeric argument each. Argument values 0-7 of <STRONG>setaf</STRONG>/<STRONG>setab</STRONG>
On an HP-like terminal, use <STRONG>scp</STRONG> with a color-pair number
parameter to set which color pair is current.
- On a Tektronix-like terminal, the capability <STRONG>ccc</STRONG> may be
- present to indicate that colors can be modified. If so,
- the <STRONG>initc</STRONG> capability will take a color number (0 to <STRONG>colors</STRONG>
- - 1)and three more parameters which describe the color.
- These three parameters default to being interpreted as RGB
- (Red, Green, Blue) values. If the boolean capability <STRONG>hls</STRONG>
- is present, they are instead as HLS (Hue, Lightness, Satu-
- ration) indices. The ranges are terminal-dependent.

- On an HP-like terminal, <STRONG>initp</STRONG> may give a capability for
- changing a color-pair value. It will take seven parame-
- ters; a color-pair number (0 to <STRONG>max_pairs</STRONG> - 1), and two
- triples describing first background and then foreground
- colors. These parameters must be (Red, Green, Blue) or
- (Hue, Lightness, Saturation) depending on <STRONG>hls</STRONG>.

On some color terminals, colors collide with highlights.
