For random colors, that is much harder!!! You will need some type of
loop to either generate each square, OR to re-color each square.
The former is probbaly a lot easier!
Something like this under unix BASH shell....
for i in `seq 1 256`; do
R=$((RANDOM%255))
G=$((RANDOM%255))
B=$((RANDOM%255))
convert -size 10x10 xc:"rgb($R,$B,$G)" miff:-
done | montage -mode Concatenate - random_colors.gif
This generates 256 random colors (in RGB space), each a 10x10 square
The numbers are generated using the Bash random number generator.
It then 'pipelines' all the images into a "montage" to 'concatenate'
them all together in a 16x16 square image.
