"You should use --window-color3 at 15% for the third color. " Why does it tell me that I have it wrong?

You always need to give us the course name and step number so we know exactly which test you are trying to pass (and a link to the step would actually be best). Also, you need to use the triple back tick method to paste our code in here properly.

On a line by itself type three back ticks. Then on the first line below the three back ticks paste in your code. Then below your code on a new line type three more back ticks. The back tick on my keyboard is in the upper left just above the Tab key and below the Esc key. You may also be able to use Ctrl+e to automatically give you the triple back ticks while you are typing in the this editor and the cursor is on a line by itself. Alternatively, with the cursor on a line by itself, you can use the </> button above the editor to add the triple back ticks.
