The key map specifies a key-to-character map to use for the Text Entry tool (Map Editor).
Notes...
When using the Multi-colour display mode, the character set may use up to four colours in any character that uses a char colour greater than 7 (yellow) in the colour palette with the restriction that the character's horizontal resolution is halved and the actual char colour can only be one of the first 8 colours.
If using the Hi-res or ECM display modes, characters can only use two colours, the background colour and the char colour which can be any of the possible 16.
On the Commodore 64, colour is not a property of character images, it is a property of the screen matrix cells in colour RAM and so a character's colour (and multi-colour status) will depend on the value assigned to the screen position (in colour RAM) the character is displayed in.
