10-1F border colour</pre>
NOTE: If you use a 16-bit write to write to the palette (e.g. LD HL,&0FFF: LD (&6400),HL then you will see the colour change as a result of first the low byte, then the high byte so that if you are writing black and then white, you will see another colour at the point of changing the colours. If you don't want to see this, then you can use the CPC OUT method but be restricted to the 27 CPC colours).
