Rainbow

Hi there! This rainbow is made entirely with code — every arc, every colour band, even the clouds are drawn by a small p5.js sketch. Why not edit the code and watch the rainbow change?

For ideas to try scroll down the code and look for the ▶ icon or the highlighted '//try' sections. For example you can:

Change the background colour from sky blue.
Change the thickness of the arcs.
Move the position of a cloud.

or anything else that you so choose!

Simply make the change to the code and press Run.

Want to go back to the original code? Easy, just press Reset.

Thanks to the p5.js community for the p5.js library (p5js.org) that runs the sketch in this editor. Note: The code in this editor is provided 'as is' for educational use only.
