Hey @web3337448869, I formatted your code. Go ahead and check out this post as a reference on how to do this.
Check this line of code:
Try changing the colors in this array and adding a new variable at the top with the RGB value of the color. For example, the RGB of purple is rgb("320,50,60") so you would change it to purple = [320, 50, 60]; And then add that new variable to the letterColors array.
