$3FFF border Idle pattern -mode- and color.

There is a way to change the color and/or -mode- (multicolor/ECM/whatever instead hires) of the IDLE pattern ($3FFF) that appears when you open upper/lower border?

first, $00 from the video matrix is only black if any associated color (register) is black....

read again what lft wrote. hires bitmap -> vram is directly related to color. and yes, its 0 :) (and thats also the case for illegal gfx mode, when BMM is selected. whether valid pixel data is still produced is completely unrelated)

okay, not really knew wtf is video matrix, in my mind it could be anything bitmap or screen, but google shows its what I usually call screen or attribute memory.

You can (obviously!) change the color by inverting whatever $3fff pattern you got and use $d021.
