It will. I (when I found you could do it on the whole screen by alternating
1F and 1C) left it on for several hours. I thought I had wrecked the LCD, but
it faded out after about two days. 

On the general subject, would it be fast enough to alternate the bsod or
blods with an image, much as is done with the 'greyscale' displays? It would
only take about 32 switches of port 10. The LCD requires 40 cycles between
rights and out(10),a takes somewhere around 20 right (the ld a,xx can be part
of the delay loop)? 60x32= 192 cyles for the whole screen to go blue.

such as this (infinite looped)

LOOP:
ld a,1F
out (10),a
ld a,1C	;? cycles
noop 	;4 cycles
noop 	;4 cycles
;noops or something else untill 40
out (10,a)
noop
noop
jp LOOP
 ;lacks an exit condition, but you get the idea.
