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.

| | | | | | +-------Green
| | | | | +-----------Blue
| | | | +---------------Intense
| | | +-------------------Flash
| | +-----------------------Extension
| +---------------------------Border
+-------------------------------0=Foreground, 1=Background
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
| +-------- bright
+---------- flash
ANSI terminal implements:
l b e f i b g r - colour
| | | +-------- bright
| | +---------- flash
| +------------ underline
+-------------- 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.
