Yes, I think it also works like that - I need to do a bit more reading.

OK, so I got done what I wanted :D

In BASIC when displaying a character you can have a foreground colour and a background colour, but the VDP lets you display 2 different colours per character line and not just per whole character. So I've written a small rountine in assembler so you can do this, which means you can have up to 16 colours per character (but only 2 colors per horizontal line)

My first z80 routine, I usualy do 6502.
