Yellow is...well, she's yellow, thats obvious. Her two colors being that and red. Covered in skin, feathers and scales, and even a bit of fur on a specific part of her.

She is 5'2 ft tall, being overall slender, with a bit of curve here and there, just to ensure that she was in fact a female.

Her body would be covered in a thick skin of yellow color, while her underbelly, vulva and breasts  were covered in a more sturdy red scales.

On her back, a pair of feathery wings, top being red, while the middle and bottom yellow just like her skin.

Tail being long and strong, ending on a red furry tip. It was flexible and very agile, being able to twist and bend at most angles.

Preferring to fly most of the time, doesn't mean she can't walk. And she indeed has to sometimes, on a pair of paws that end up with claws.

Whats with her most of the time is a proud smirk, always proud and thinking of herself above anyone else, obviously thinking of herself as someone above the masses.
