The memory address 53280 ($D020) is used for the frame color of the screen and is set under BASIC with POKE 53280,X
. All 16 colors available to the C64 can be used.
The standard (start up) color of the C64 is:
- Background color: dark blue (6)
- Screenframe: light blue (14)
- Text color: also light blue (14)
Machine languages can manipulate the screen frame in order to show chars, sprites and raster bars.
