Physical colour numbers are used as the short physical colour in the VDU 19
  7  6  5  4  3  2  1  0
+
command, and used in the COLOUR and GCOL commands on platforms without a
+---+---+---+---+---+---+---+---+
+
palette. The colour number is a bitmap of the colour to select. When
|F/B| B | E | F | I | B | G | R |
+
implementing an operating system interface on other platforms this mapping
+---+---+---+---+---+---+---+---+
+
must be adhered to.

The border is specified by using -1 as the logical colour number.
 
 
The following example sets the border colour to green.
 
 
    VDU 19,-1,2,0,0,0
 
 
 
The alternative mode provides an 'analogue' palette by allowing you to set
 
the Red, Green and Blue intensities to any value between 0 and 63. The
 
format of the VGA 'analogue' colour palette command is shown below.
 
 
    VDU 19,logical,-1,red,green,blue
 
 
 
If bit 7 of the logical colour number is set (values 128 to 143), then the
 
enhanced palette is used and the physical colour is taken to be the IBM
 
colour value.
 
 
For example, the following command will set logical colour 1 to green.
 
 
    VDU 19,129,2,0,0,0
 
 
The text enhanced palette is the same as the graphics enhanced palette.
 
 
6-bit RGB colours
 
In the 6-bit RGB mode you set the physical colour by specifying the values
 
of the individual red, green and blue components as numbers in the range 0
 
(minimum) to 63 (maximum). Hence the value 0,0,0 corresponds to black and
 
the value 63,63,63 corresponds to peak (intensified) white.
 
 
To select a logical colour to one of these physical colours you must use the
 
VDU 19 command:
 
 
    VDU 19,logical,-1,red,green,blue
 
 
This mode is provided for compatibility with BBC BASIC (86).
 
 
8-bit RGB colours
 
In the 8-bit RGB mode you set the physical colour by specifying the values
 
of the individual red, green and blue components as numbers in the range 0
 
(minimum) to 255 (maximum). Hence the value 0,0,0 corresponds to black and
 
the value 255,255,255 corresponds to peak (intensified) white.
 
 
To select a logical colour to one of these physical colours you use either
 
the VDU 19 command or the COLOUR statement:
 
 
    VDU 19,logical,16,Red,Green,Blue
 
    COLOUR logical,Red,Green,Blue
 
 
 
  0 1 x x x b g r -
 
  1 0 x x x b g r - background colour
 
  1 1 x x x b g r - border colour

Physical colour numbers are used as the short physical colour in the VDU 19 command, and used in the COLOUR and GCOL commands on platforms without a palette. The colour number is a bitmap of the colour to select. When implementing an operating system interface on other platforms this mapping must be adhered to.

 This gives:
  0 0 e f i b g r - &00+n - foreground colour
  0 1 e f i b g r - &40+n - extension
  1 0 e f i b g r - &80+n - background colour
  1 1 e f i b g r - &C0+n - border colour
 
 The BBC implements:
  l x x x f b g r - colour
          +-------- flash
 
 The ZX Spectrum implements:
  l b e f i b g r - colour
    | | | +-------- bright
    | | +---------- flash
    | +------------ change only flash/bright
    +-------------- border
 
 The Commodore implements:
  l b x f i b g r - colour
    |   | +-------- bright
    |   +---------- flash
    +-------------- border
 
 DOS/Windows implements:
  l x x f i b g r - colour

    +-------------- inverse

The BBC uses b3=flash, whereas all platforms other than the BBC uses b4=flash. For visual compatibility, programs could use 0-7 for non-flashing colours and 24-31 for flashing colours. On the BBC these will be flashing colours, on other platforms these will be bright flashing colours where supported.
