Console Functionsfunctiondocumented

Syntax

Declare Function Color ( ByVal foreground As ULong , ByVal background As ULong ) As ULong

Parameters

NameDescription
foregroundthe foreground color to set
backgroundthe background color to set

Return value


Returns a 32-bit value containing the current foreground color in the Low Word and the current background color in the High Word.
In hi/truecolor modes, only the foreground color is returned, taking up the whole 32 bits. Instead, see ScreenControl to return the current graphics mode color (foreground and background).

The old color values can be retrieved at the same time as setting new ones.

Description


The Color statement sets the current foreground and/or background colors. Circle, Draw, Line (Graphics), Cls, Paint, Print, PReset and PSet all use the last colors set by this function when you don't specify a color to them, where applicable. The color values that Color accepts depend on the current graphics mode.

ModeMeaning
1foreground is screen color (ranging 0-15). background is the emulated CGA palette to be used: 0 (green, red, and brown), 1 (cyan, magenta and white), 2 (same as 0, but with bright colors) or 3 (same as 1, but with bright colors)
2, 11foreground is a color index in current palette (ranging 0-1). background is a color index in current palette (ranging 0-1).
7, 8foreground is a color index in current palette (ranging 0-15). background is screen color index in current palette (ranging 0-15).
9foreground is a color index in current palette (ranging 0-63). background is screen color index in current palette (ranging 0-63).
12foreground is a color index in current palette (ranging 0-15). background is a color index in current palette (ranging 0-15).
13 and upforeground is a color index in current palette (ranging 0-255). background is a color index in current palette (ranging 0-255).


If you are using a color depth higher than 8bpp, foreground and background are direct RGB color values in the form &hAARRGGBB, where AA, RR, GG and BB are the alpha, red, green and blue components ranging &h00-&hFF (0-255 in decimal notation). While in hi/truecolor modes, you can use the RGB or RGBA macro to obtain a valid color value.
A Default Palette is automatically set when entering a Screen (Graphics) mode.

Remarks

Usage


Color [foreground] [, background]
result = Color [( [foreground] [, background] )]

Differences from QB


  • Direct color modes were not supported in QB.
  • There is no border argument.
