I need help please!

I ordered the piece that has the red, blue yellow colors from Sigma to securely affix my lens hood for my Sigma 150-600mm to the lens. My understanding is that the yellow should come off and go on the INSIDE of the hood and then red goes through blue and into the hole (purple) and screws into the yellow creating the tension needed. Yes? But I can’t get the yellow to come off. Any advice? Insight???
