Yellow is Claudia.

Actually, orange is Claudia. And there's got to be some blue in there, too. (Except a non-masculine, more cloudy and pastel-y blue.) This is an annoying prompt.
Claudia is the really cool, speckled paint that friends and siblings fight over at the Mad Potter-- which may have closed, like, years ago. My point is she's speckled. With probably an orange base.
To start with the obvious: Claudia is Henry Clay's Little Fireball. She's tiny and adorable, and independent and comfortable with herself and the world around her. She's also hilarious! And super-smart, in matters of Chelsea's life as well as Language and Composition multiple choice questions. She has the prettiest collection of sweaters, and can pull off ponytails like nobody's business.
Looking deeper,
You know, there is no deeper. Not to say Claudia's not deep. She's just so yellow! She radiates personality and charisma and Fireballability. Her blue represents how easygoing she is, but also her intellect. Her orange speckles are the incredible humility that may or may not mask that intellect, as well as her uniqueness in this quality and others (which include: being so tiny, NEVER complaining, having something nice to say about-- seriously-- everyone).
This is an ANNOYING prompt.
But you're fun to talk about, Miss Claudia!
