Cilla now was ready to change the red tie into a yellow tie. She knew that if she focused on "Hufflepuff" then the spell might not work because when Cilla thought of that particular house, the colour yellow was not usually in those thoughts.

Instead, the young witch decided to focus on sunflowers, the sun and canaries. These made her think instantly of the colour yellow. Cilla pointed her wand at her red tie, focusing on a mental image of a field of sunflowers and clearly said, "Colovaria."

The tie was now a bright yellow.
