COLOR Statement
Purpose:
To select display colors
Syntax:
COLOR [foreground][,[background][,border]]
COLOR [background][,[palette]]
COLOR [foreground][,[background]]
Comments:
In general, COLOR allows you to select the foreground and background colors for the display. In
SCREEN 0 a border color can also be selected. In SCREEN 1 no foreground color can be selected,
but one of two four-color palettes can be selected for use with graphics statements. The different
syntaxes and effects that apply to the various screen modes are described below:
Mode Effect
SCREEN 0 Modifies the current default text foreground and background colors, and the
screen border. The foreground color must be an integer expression in the range
0-31. It is used to determine the "foreground" color in text mode, which is the
default color of text. Sixteen colors can be selected with the integers 0-15. A
blinking version of each color can be selected by adding 16 to the color number;
for example, a blinking color 7 is equal to 7 + 16, or 23. Thus, the legal integer
range for foreground is 0-31.
The background color must be an integer expression in the range 0-7, and is the
color of the background for each text character. Blinking colors are not permitted.
The border color is an integer expression in the range 0-15, and is the color
used when drawing the screen border. Blinking colors are not permitted.
If no arguments are provided to COLOR, then the default color for background and
border is black (COLOR 0), and for foreground, is as described in the SCREEN
statement reference pages.
