Yellow

The first time Bellatrix Black sees yellow for what it means is when she meets Alice Fortescue on the Hogwarts Express. It means friendship and warmth, something Bellatrix craves in grayscale life. The colour bleeds through into her black and white world, she finds it in places it shouldn't be and she finds it in the form of Adelpha Carrow. A girl who is so yellow, she is like the sun and like the sun she pulls Bellatrix into her orbit.
