1. draw the two clouds under rainbow
   • create a function of clouds with arc()
   • fill the shapes with beginShape(), endShape()
2. draw the rainbow
   • each rainbow will be arcs.
   • curves’ shapes are fixed, while colors changes over time. So build variables for their color. Add function that sets color (use arrays or for loop to set the changing color for curves.)
   • have three rainbow with different weights presenting second, minute and hour.
3. check to see if the change of color corresponds to time.

here’s my sketch
