Emily:

code generates random colored concentric circles (see example)

add white background color

create random number variable between 0 and width of canvas (but should be aligned in a perfect and even row)

create random number variable between 0 and height of canvas (also should be aligned in a perfect and even column)

create random number variable between 0 and 255 for random r, g, & b color (the outermost ring of circle)

create random number variable between 0 and 255 for random r, g, & b color (the second ring of circle)

create random number variable between 0 and 255 for random r, g, & bcolor (the third ring of circle)

create random number variable between 0 and 255 for random r, g, & b color (the center of circle)

set fill color using randomized r, g, & b variables

create ellipse for each ring (approx. 80 for outermost, 60 for second, 40 for third, 20 for center) at position of x and y variables

(each set of randomized layers of concentric circles would however have to share the same center point)
