Hi bastian!

The first half of your code looks good!  But just so you know, there should only be 1 for loop in this project.  Notice how you're not using the second for loop for anything?  It isn't needed, so you can get rid of it.  After that, you should be good!  If you continue to get an error after deleting the second loop, just play around with the increments of r, g, and b.  This project want's some specific values.

Hope this helps and happy coding!  Let me know if you have any other questions :)

the right code is:

noStroke();
background(0, 0, 0);
var r = 255;
var g = 90;
var b = 0;

for (var i = 0;i<360;i+=30) {
fill(r, g, b);
r-=1;
g+=1;
b+=1;
pushMatrix();
translate(200, 200);
rotate(i);
rect(0, 0, 150, 15);
popMatrix();
}

thank you so much

this helped so much!!
