White is a colour that is connected with wisdom and knowledge in many cultures, and I think it’s a perfect fit for a superhero like Lady Ceres who can see the truth in any situation and who knows exactly who she is and what she stands for. I would also picture her with a golden tiara, to symbolize strength, power, and beauty. Her costume would be light and airy, reflective of the freedom that comes with knowing your own inner worth. She’d fly high in the clouds like a phoenix!
