hi, again, i not see 2 sets…
what i see in your program was, that you print a array(list) of circles 2 times / on same position…
if you use my code get more random colors, but not 2 sets.
how should that look, and what has that to do with the “mouseover”
you could make all in the upper half of the picture and print them again with y + 250
and there you could allow ( for all the second set/print )
a other color by mouse position…
fill(e[i]+mouseX/5,100,100); or in the intensity…
